LONDON (Reuters) - British Prime Minister David Cameron said on Thursday that he cannot see an end to the government's austerity program while Britain tackles its huge budget deficit amid deteriorating economic conditions.
Cameron indicated that Britain's program of spending cuts, initially planned to take five years, could last until 2020.
"This is a period for all countries, not just in Europe, but I think you will see it in America too, where we have to deal with our deficits and we have to have sustainable debts. I can't see any time soon when ... the pressure will be off," Cameron said in an interview with the Daily Telegraph.
When the Conservative/Liberal Democratic coalition took power in 2010, it introduced an austerity program of increased spending cuts and tax increases that was intended to finish by 2015.
The program was extended to 2017 late last year, however, and is expected to save the government about 110 billion pounds ($171.85 billion) in total.
"I don't see a time when difficult spending choices are going to go away ... we are in a very difficult situation," said Cameron.
Britain's budget deficit peaked at over 156 billion pounds in 2009/10 or 11 percent of GDP.
"I don't deny for a minute that it is a lot tougher than the forecasters were expecting," he said.
In a broad interview, covering, among other subjects, the economy, the coalition and the Olympic Games, Cameron said it had been a "very tough time to be in Government."
Britain was hit hard by the 2007-2009 financial crisis and had to spend tens of billions to bailout major banks.
The recovery from the steep slump has been weak, with stuttered growth, soaring unemployment and a squeeze on living conditions and household budgets for ordinary Britons.
"We've had one of the longest and deepest recessions for decades in Britain. It was an incredibly tough set of circumstances and it has proved very hard to get out of those situations," he said.
On the issue of Europe, Cameron said he did not believe that Britain should leave the EU and that he would never campaign for an "out" vote in any referendum.
He indicated that he would seek to negotiate a "new settlement" with Europe, which will be put to a referendum rather than offering an in-out vote.
