LONDON (AP) — The Latest on Britain's referendum on whether to leave the European Union (all times local):
UK broadcasters are predicting that Britain has voted to leave the 28-nation European Union in a historic referendum.
With 329 of 382 counting centers reporting results, the "leave" side is ahead by over 900,000 votes.
The results of Britain's vote Thursday will seriously hurt the continental unity forged after World War II. The U.K. is the first major country to decide to leave the bloc, which evolved from the ashes of war as the region's leaders sought to build links and avert future hostility.
The British pound has tumbled to a 31-year low as the results of the vote spook global markets.
UK broadcasters predict that Britain has voted to leave the 28-nation European Union in a historic referendum.
With 323 of 382 counting centers reporting results, the "leave" side is ahead by over 900,000 votes.
As "leave" votes pour in from Britain's historic vote on European Union membership, post-mortems are already being produced. One expert says the "remain" side had suffered from "a degree of complacency."
Tim Oliver, a fellow at the London School of Economics' IDEAS foreign policy think tank says "the campaign failed to connect to ordinary people, seemed too much of an elite and London-based one."
Oliver says the vote wasn't just about Europe — but also about a popular British backlash against the capital and its elites. He says "the EU was one of the things kicked by this, but there were lots of other things such as a general anti-establishment feeling, anti-London feeling."
U.K. Independence Party leader Nigel Farage now says he thinks the "leave" side will win in Britain's historic referendum on European Union membership.
Farage has pressed British Prime Minister David Cameron's Conservative government to hold the referendum — and the vote has deeply split the ruling party.
To the cheers of supporters, Farage says "the dawn is breaking on an independent United Kingdom! If the predictions now are right, this will be a victory for real people, for ordinary people, a victory for decent people!"
Farage says June 23 will go down in history as the nation's new independence day and he hopes the victory will bring down what he considers the failed European Union project.
The "leave" campaign has a lead over the "remain" side with about 70 percent of voting districts reporting early Friday.
British pound tumbles to a 31-year low as EU vote results show the 'leave' side in lead by over 400,000 votes after 244 of 382 counting centers report results.
The British pound is plunging as results come in from the EU referendum, falling to its lowest level since January 2009 hours after hitting its highest level for the year moments after the polls closed.
Uncertainty over the outcome of Britain's vote on European Union membership is keeping world currency markets on edge Friday.
The British currency fell as low as $1.3642 hours after hitting a 2016 peak of $1.50.
British voters seeking to leave the European Union hold the lead as results are being tabulated Friday morning.
With exactly half of U.K. voting districts reporting official results from Thursday's referendum, the "leave" campaign has received 52 percent of support — more than 7.7 million votes — versus 48 percent for the "remain" camp, which has 7.2 million.
Analysts say anti-EU sentiment is running unexpectedly strong in northern English cities hits hard hit by industrial decline and job losses, with broad swathes of England and Wales recording "leave" majorities. But they caution that the "remain" side could regain the lead when more districts are declared in Britain's colossal population center, London.
The close vote in Britain's referendum on EU membership made for stomach-churning twists and turns as the "remain" and "leave" camps traded the lead in the official count.
At a "remain" party in East London, Labour Party councilor Andrew Cregan said he and his guests had been through "a bit of a roller-coaster ride."
He says "it was quite positive to begin with" since financial markets appeared to be pointing to a "remain" victory. But when northeast areas of Sunderland and Newcastle reported a surge in support for "leave," he said the mood at his party soured quickly.
Cregan said the partygoers had mostly gone home but he couldn't sleep until he saw the final result.
"I'm fearful of the result," he said. "This is the most important decision that people are voting on in my lifetime. And I don't think that many people who have cast a vote today understand what they're casting a vote on, or understand what's at stake."
Voters seeking a British exit from the European Union are leading, as one-third of official results have been declared in Britain's historic referendum.
As Friday's vote counting continued overnight, the "leave" side led with 50.9 percent of votes with "remain" trailing on 49.1 percent. The gap between the two sides stood at about 191,000 votes with 144 of the 382 count centers reporting results.
Early results from London are showing strong support for the campaign to keep Britain within the European Union.
A win for the pro-European forces in the cosmopolitan capital was expected, but the high margins of victory in some London areas have given a little confidence to the "remain" camp amid poor results elsewhere.
The key will be turnout in a city that saw massive summer downpours on referendum day Thursday that caused some train and traffic chaos.
The south London boroughs of Wandsworth and Lambeth saw big margins and high turnouts, with 75 percent and 79 percent backing the "remain" side respectively.
A slew of new voting results from England, Wales and London are supporting the campaign to pull Britain out of Europe — and that means warning signs for the "remain" camp.
The first four results from Wales have shown majorities for the "leave" camp, even in Swansea, an urban area where "remain" had been expected to perform well.
The "leave" campaign also appeared to be doing better-than-expected in northeast England, where voters overwhelmingly chose to leave the EU.
Early indications showed high turnout in London, where the "remain" side is expected to dominate, but some commentators said turnout would have to be even higher to counterbalance the "leave" vote elsewhere.
The "leave" side has become the betting favorite for the first time in the British referendum campaign on whether to leave the 28-nation European Union.
The Betfair market predicts a 51 percent chance of Britain leaving the EU, after stronger-than-expected results for the out campaign in several areas of England and Wales.
Bookies' odds on Brexit also shortened to as short as 6-5. They had been 5-1 only hours earlier, as polls pointed to a "remain" win.
The results from the British referendum on European Union membership are still far too incomplete to draw any solid conclusions.
Still, a series of better-than-expected results for the "leave" camp appears to have convinced some people that the drive to pull Britain out of Europe has a real chance of winning.
Google Trends, an arm of the search engine giant, says there has been a 250 percent spike in searches for the phrase "what happens if we leave the EU" in the past hour.
The neck-and-neck nature of the British referendum vote count had politicians and pollsters predicting an all-nighter for a nervous nation.
Senior Labour official John McDonnell is predicting a final result which will put both sides within one or two percentage points of each other.
One pollster described the vote as hanging "on a knife edge."
Former Labour leader Ed Milliband told Sky News that the vote would be very close, saying "I think this is going to be a long night."
The British pound is getting whipsawed by volatile trading as initial results from the vote on whether the U.K. should remain in the European Union showed the race is too close to call.
The currency surged shortly after the polls closed Thursday, climbing to a 2016 peak of $1.50 after a leading proponent of the "leave" vote indicated he thought his side was heading for a loss. But the pound sold off — falling 4 cents in 5 minutes — after counts from cities including Newcastle and Sunderland showed the result was far from certain.
The pound was trading at about $1.453.
The "remain" side has scored only a narrow victory in the large northern English city of Newcastle.
Official figures show that 50.7 percent of voters in Newcastle backed U.K. membership in the European Union and 49.3 percent wanted to leave.
The odds of a "remain" victory fell from almost 90 percent to 72 percent on the Betfair exchange, and the pound — which had soared after polls suggested a "remain" victory — fell by 1.5 cents against the dollar to $1.4830.
University of Strathclyde political scientist John Curtice told the BBC "it may be possible that the experts are going to have egg on their face later on tonight. It may be the first sign that the 'remain' side are not going to do as well as those early polls suggested."
12:05 a.m. Friday
The vote counting in the northern England area of Leeds and neighboring Kirklees was briefly abandoned for a minute's silence in honor of lawmaker Jo Cox, who was stabbed and shot to death in the run-up to the referendum.
The killing of Cox, a parliamentarian with Britain's opposition Labour Party, shocked the country and prompted both the "remain" and the "leave" camps to suspend their campaigning.
Television footage showed ballot papers being set aside as counters stood up and bowed their heads late Thursday before resuming their work. Cox's death has loomed large over the vote, darkening the tone of an already fiercely fought campaign.
UK Independence Party leader Nigel Farage says "the euroskeptic genie is now out of the bottle and it will not be put back."
Farage appeared to walk back on his apparent concession after the British polls closed Thursday night on the EU referendum, telling reporters in London that "maybe just under half, maybe just over half of the country" had voted to pull Britain out of the EU.
Still, he struck a downbeat note, saying the government's decision to extend the voter registration deadline before the vote had probably tipped the scales in the "remain" camp's favor.
His comments already seemed to look past Thursday's vote to further fights ahead.
Farage says "win or lose this battle tonight, we will win this war." He says "we will get our independence back. We will get our country back. We will get our borders back."
Gibraltar, the first British territory to announce its EU referendum result, says an overwhelming 95.8 percent of its voters have backed remaining in the bloc.
Gibraltar's leader, Chief Minister Fabian Picardo, says a lopsided pro-EU vote was always expected because of the British overseas territory's dependence on maintaining easy cross-border travel and trade with neighboring EU member Spain.
The strategic spot overlooking the western entrance to the Mediterranean was seized by Britain in 1704. Today the territory, barely 3 square miles (7 square kilometers) in size, is home to more than 30,000 British citizens.
Gibraltar electoral officials say of the 20,172 people who voted, 19,322 chose to remain in the EU.
Pollster Ipsos MORI says a survey conducted on Wednesday and Thursday suggests the "remain" side will win Britain's EU referendum by a margin of 54 percent to 46 percent.
Earlier Thursday, the firm released a poll conducted Wednesday that indicated a 52-48 victory for "remain." That phone poll of 1,592 people had a margin of error of plus or minus three percentage points.
The firm's chief executive, Ben Page, said continued polling on Thursday — referendum day — suggested a bigger swing to "remain" that gave the 54-46 result.
Britons were voting on whether or not to leave the 28-nation European Union.
Early reports suggest a very high turnout in Britain's EU referendum.
The first area to officially declare its turnout was Gibraltar, a British enclave at the southern tip of Spain that is expected to heavily back a "remain" vote. There, almost 84 percent of eligible voters turned out to cast ballots.
Local counting officers in several areas say turnout was higher than in last year's general election, which was 66 percent.
High turnout is expected to boost the "remain" vote, because "leave" supporters are thought to be more motivated. But high turnout in working-class areas that typically have lower tallies could also boost the "leave" vote.
The last time Britain had a referendum on its EU membership, in 1975, turnout was 65 percent.
Dozens of Conservative lawmakers who called for Britain to leave the European Union have signed a letter saying Prime Minister David Cameron should stay in office whichever side wins the membership referendum.
The letter signed by 84 legislators says "whatever the British people, decide you have both a mandate and a duty to continue leading the nation implementing our policies."
That leaves more than 60 Brexit-supporting Tory lawmakers who did not sign.
The referendum on the EU has deeply split Cameron's Conservative party. Cameron led the "remain" campaign, but senior figures including Justice Secretary Michael Gove and former London Mayor Boris Johnson backed a "leave" vote.
Many observers feel Cameron will have to resign if Britons vote to leave the 28-nation bloc.
Reports that the "remain" side could be headed to victory in Britain's referendum on European Union membership have sent the British pound surging more than 1 percent to $1.50.
Polling station workers in Britain were seen rushing ballot boxes to be counted after the polls closed at 10 p.m. Thursday. Results are expected Friday morning.
British Electoral Commission Chair Jenny Watson says the first stages of the vote counting process are now underway in Britain's referendum on membership in the European Union.
Polling station workers were seen rushing ballot boxes to be counted.
The vote is expected to be close in the battle over whether Britain should stay in the European Union or leave the 28-nation bloc. Watson says final results should come in Friday morning.
UK Independent Party leader Nigel Farage, a leader of the "leave" campaign tells Sky news "it looks like 'remain' will edge it" but most British politicians said it was impossible to know at this time.
UK Independent Party leader Nigel Farage tells Sky news "it looks like 'remain' will edge it" in Britain's referendum on whether to stay in the 28-nation European Union.
Polls have closed in the historic vote and counting was beginning immediately Thursday.
Farage was one of the leaders of the 'leave' side in the referendum.
Polls have closed in Britain's historic referendum to decide whether the country remains in the European Union.
The voting Thursday was hampered by torrential rain and some flooding in London and parts of southeast England.
Counting will begin immediately with results expected Friday morning. Final polls suggested a close race.
Prime Minister David Cameron led the campaign to keep Britain inside the 28-nation bloc. He argued that participation strengthens Britain's economy and security.
Former London Mayor Boris Johnson and others on the "leave" side said Britain would be stronger and wealthier on its own.
The divisive campaign saw heated rhetoric on both sides and split the ranks of Cameron's Conservative Party.
Both sides in Britain's referendum campaign are urging supporters to get out and vote, with less than an hour to go until polls close.
Britain Stronger in Europe tweeted that people should vote to remain for "a brighter future for your children and generations to come."
Vote Leave chief executive Matthew Elliott urged people in the "heartlands" outside London and Scotland — expected to be big "remain" strongholds — to make an extra effort.
Former London Mayor Boris Johnson, who leads the "leave" campaign, said polls suggested the outcome would be close. But he says "all the information is that turnout is good in areas where we need it to be."
Polls close at 10 p.m. (2100GMT).
Rain and thunderstorms are causing canceled trains and slow journeys in the London area as people travel home from work.
Southeast England was hammered by up to 1.75 inches (4.6 centimeters) of rain overnight — roughly the average for all of June — and another band of rain swept through on Thursday afternoon.
Signal failures caused by flooding shut down sections of the London Underground subway system and several train lines into the capital. The Rail Delivery Group says train services will be severely disrupted Thursday evening and people should head home early if they can.
The disruption could hit the turnout for Britain's referendum on whether to stay in the 28-nation European Union as many people go to polling booths after work. The polls close at 10 p.m. (2100GMT).
Italy's finance minister says whatever British voters decide, there's already a fracture with the European Union.
Minister Pier Carlo Padoan is being quoted as saying at a forum in Rome on Thursday that no matter what happens, it will be impossible to assert "let's pick up as if nothing" happened.
The Italian news agency ANSA quoted him as saying that as Britons vote to decide whether to exit or stay in the EU, that "the fracture has already happened and in a very clear-cut way." Padoan said the consequences will vary, depending on the outcome, but "there won't be the same path as if there hadn't been the referendum initiative."
The European Union's migration commissioner has described the British people as an "integral part of our European family" as voters decide whether to remain in the bloc.
Dimitris Avramopoulos told a finance conference near Athens that "this ... is one of the most crucial moments of modern European history.
"The citizens of the United Kingdom, an integral part of our European family, are deciding whether they want to remain or exit our common European home."
Europe's migration crisis played a prominent role in the campaigning ahead of Thursday's referendum by those who want Britain to leave the EU.
Avramopoulos said: "Let's be frank: Europe found itself unprepared in the middle of an unprecedented migration and refugee crisis." He added that the number of arrivals by migrants and refugees in the EU this year had been drastically reduced by tougher border policing and a deportation agreement with Turkey.
The founder of anti-secrecy site WikiLeaks plans to host a live, online punditry show about Britain's referendum on whether to stay in the EU.
Julian Assange has been holed up in the Ecuadorean Embassy in London since 2012.
He is wanted for questioning by Swedish police over rape allegations stemming from his visit to the country in 2010. He denies all the accusations against him made by two women.
The Australian recently said he was "pretty much" in favor of Britain leaving the European Union, arguing that its membership was holding the 28-nation bloc back.
Guests billed for Assange's show include Greece's ex-finance minister Yanis Varoufakis, musician Brian Eno and "former CIA officers." It is scheduled to run from 1900 GMT Thursday until early Friday morning, when referendum results are expected.
England soccer captain Wayne Rooney isn't following David Beckham's lead in announcing how he voted in the referendum about whether Britain remains in the European Union. Or even if he voted at all.
Asked Thursday if he voted, Rooney said, "I'd like to keep that private."
Speaking at England's training base north of Paris during the European Championship, Rooney said, "The option has been there for the players (to vote during the tournament) — I don't know which ones have, which ones haven't."
On Tuesday, Beckham, a former England captain, said he would be voting for Britain to remain in the European Union, highlighting how his successes with English club Manchester United owed much to European players and how welcoming he later found playing soccer for continental clubs.
A sense of uncertainty seemed to hang over central Edinburgh in Scotland as voters pondered how a vote for Britain to leave the European Union might affect the Scottish independence movement.
Some believe a British decision to leave the EU bloc in Thursday's referendum might trigger another Scottish vote on independence like the one that fell short in 2014.
Clayton Thomson, a 30-year-old bar manager, said Scottish nationalists might call another referendum if a "leave" vote takes Scotland and the rest of Britain out of the European bloc.
Retiree Robert McCallum, 84, also believes a British exit, or Brexit, would increase calls for Scotland to sever its ties to Britain.
The popular Scottish National Party, which spearheads the Scottish independence movement, advocates keeping Britain inside the EU.
German Chancellor Angela Merkel says the European Union should respond in a calm and inclusive way to whatever result emerges from the British referendum on EU membership.
Merkel said after meeting her Austrian counterpart in Berlin Thursday that she doesn't favor discussing the consequences in small groups of EU countries. She said: "overall, I think discussions must now be continued with 28 (countries) if possible and otherwise with all countries — that would be 27 — but my hopes are pinned on it possibly being able to remain 28."
She noted that an already-scheduled EU summit starting next Tuesday will give countries "the opportunity to discuss all together and calmly how we continue to implement our agenda."
Denmark's prime minister says "it would be a tough job" to work out what would happen if British voters decide to leave the European Union.
Lars Loekke Rasmussen says work would start Friday, adding he hopes for "a peaceful divorce" should Britain leave the bloc that it joined at the same time as Danes in 1973. The Scandinavian nation has opted out of parts of EU treaties for fear of losing sovereignty but it has no plans for a membership referendum.
Norwegian Foreign Minister Boerge Brende, whose country twice has rejected EU membership, wrote Thursday on Twitter "Fingers crossed for (hashtag) remain."
The oil-rich nation has signed up to the European Economic Area agreement and thereby access to the EU's huge single market.
Hungary's foreign minister says it would be against the interests of his country and of the European Union for Britain to leave the EU.
Foreign Minister Peter Szijjarto on Thursday described Britain as a "pragmatic voice" in the debate about the future of the EU, often in line with Hungary's vision of the 28-member bloc, adding that its exit would be "contradictory" from a political and economic perspective.
Hungarian Prime Minister Viktor Orban earlier this week bought a full-page ad in a British newspaper The Daily Mail, to say that "Hungary is proud to stand with you as a member of the European Union."
An estimated 300,000 Hungarians live in Britain.
An opinion poll conducted on the eve of Britain's referendum shows a narrow lead for those who want Britain to remain a part of the European Union.
Polling firm Ipsos MORI says the "remain" camp enjoyed a four-point lead ahead of the vote. But the polling firm's chief executive, Ben Page, says 13 percent of those polled said they still might change their minds.
The poll of 1,592 people was conducted for the Evening Standard newspaper and was completed Wednesday night.
Page said Thursday that heavy rain in London may affect the vote, because the British capital is seen as a "remain" stronghold.
Recent opinion polls in Britain have been unreliable.
Betfair says momentum has moved to the "remain" camp in a referendum on whether or not Britain will remain in the European Union.
The betting market says the probability that the country will remain now stands at 86 percent, with a British exit or Brexit given just a 14 percent chance. Betfair says some 55 million pounds ($80 million) has now traded on the market, making it their biggest market to date. Their previous high was the 2012 U.S. presidential election at 40 million pounds.
The FTSE 100 gained 1.5 percent in early trading to 6,355.64, buoyed by sentiment that the uncertainty caused by a potential Brexit may be receding.
The British pound and stock markets are rallying in morning trading in Europe, an indication that investors are betting that Britain is more likely to vote to "remain" in the European Union.

Experts say that an exit from the EU would hurt the pound as well as global stock markets, at least in the short term.
While exit polls are not allowed to be published during Thursday's vote, which closes at 10 p.m. (2100 GMT) some financial companies have reportedly commissioned private exit polling services to help guide their trading.
Germany's biggest-selling newspaper has an offer for the British: stay in the European Union and we'll stop making jokes about Prince Charles' ears and reserve you places by the hotel pool in the morning.
The mass-circulation Bild daily dipped into decades of clichés about British-German relations for its front page Thursday, headlined "Dear Britons, if you stay in the EU ..."
Among the offers: "We won't use any sun cream at the beach any more — out of solidarity with your sunburn!" And "we'll push through an EU directive banning foam on beer!"
Topping the list was an offer that would stick in any Germany soccer fan's throat: "Even we will recognize the Wembley goal!" That's a reference to England's third goal in its 1966 World Cup final victory, which Germans maintain didn't cross the goal line.
Voters in parts of Britain are facing floods and torrential downpours as they cast their ballots in a referendum on whether or not to remain in the European Union.
The capital, London, is expecting a month's rainfall in a few hours Thursday. Overnight thunderstorms flooded some streets, homes and businesses. Commuters also suffered disruptions.
London's Fire Brigade says it received hundreds of calls related to the weather, including reports of lightning strikes and rising water that trapped vehicles.
The Environment Agency has issued four flood warnings and 22 flood alerts across the southeastern part of the country.
Sunny weather is predicted for much of the rest of the country.
Pollsters say turnout will be a critical factor in the vote. A large turnout will favor the "remain" campaign as those who waver at the end tend to go for the status quo.

The Conservative leader had headed the campaign to have Britain stay in the 28-nation bloc.
The leader of the opposition Labour Party, Jeremy Corbyn, also cast his ballot in the referendum, which is considered historic because it will have an impact on generations to come.
Australian Prime Minister Malcolm Turnbull says there will be a big impact on the global economy if Britain votes to leave the European Union.

Polls are open until 10 p.m. (2100GMT), with results due early Friday.
The referendum has exposed deep divisions over issues including sovereignty and national identity.
