(Reuters) - The campaign to get Britain out of the European Union has a 2-point lead over the "Remain" campaign, polling firm TNS said on Monday, citing a poll conducted in the third week of May.
Forty-three percent of respondents wanted Britain out of the EU, while 41 percent wanted it to stay, according to the online poll of 1,213 Britons. The difference was within the poll's margin of error. Sixteen percent of respondents were undecided.
The TNS poll was carried out between May 19-23, a month before the EU referendum date.
Britons vote on June 23 on whether to remain in the 28-member bloc, with important implications for its trade, economic and political status.
The campaign to stop Britain voting to leave the EU has seen its lead shrink recently, with polls in the past week showing gains for "Leave".
Sterling fell sharply last Tuesday when both an online and a telephone poll for ICM showed a 3-percentage-point lead for the "Leave" campaign.
