Prime Minister David Cameron was dealt a double blow today, as a new TNS poll showed more voters want Britain to leave the European than to remain, and just one in seven voters think Cameron's renegotiation of Britain's relationship with the European Union has been successful.
The poll results were published this morning as Cameron struggles to hammer out a reform deal with European leaders in Brussels.
TNS polled more than 1,000 voters last weekend, with 36 per cent of respondents saying they would vote to leave compared to 34 per cent who would back the UK remaining in the EU.
Seven per cent said they would not vote, while nearly one-quarter of respondents said they were still undecided.
But despite the apparent lead for the Leave camp, TNS found that most people thought the referendum would ultimately result in the UK remaining in the EU, with 38 per cent of respondents saying they thought the UK would vote to remain in the EU compared with 28 per cent who said they thought the UK would vote to leave.
In a disappointing result for Cameron, however, TNS found that just 14 per cent of voters felt the Prime Minister's renegotiation efforts had been successful, compared to 37 per cent who said the opposite. One in five said the UK was "weaker after the renegotiation than before" and almost 40 per cent said they believed Cameron's efforts had "made no difference at all".
