Ed Miliband: no referendum on Britain's membership of the EU Mr Cameron has promised to seek a "new settlement" for Britain in Europe, then put the deal to voters for their consent. "I think that it's incredibly dangerous what David Cameron's doing," Mr Milliband said on the programme, which was presented by James Landale after Mr Marr suffered a stroke. I think he is essentially sleepwalking us towards the exit door from the European Union. The last thing we should do is start to say for some date five, six , seven years hence, let's decide now to have an in/out referendum. Although Mr Miliband failed to guarantee that he would not consider a referendum after the 2015 election, he said he believes it would be a "bad idea." He said that Mr Cameron is only making the pledge to negotiate a new settlement for the UK in Europe because of the threat from Ukip as well as unrest among Conservative backbenchers. "We know why this is happening," Mr Miliband said. He's worried about the threat from Ukip and he's worried about what's happening in his own party. It's the wrong thing to do, it's not in the national interest. But I'm very clear, the question for now is should we have a referendum? Should we commit to a referendum? Should we promise one? And I'm saying very clearly to you, no is the answer. I'll set out at the election what our position is on the issue. I'm not going to speculate about years hence but I'm giving you a very clear view that it's the wrong thing to do. A poll has shown that Mr Cameron could slash Ukip's support by more than a third if he promises an in-out referendum on EU membership Research by ComRes for the Sunday People found 63% of the public want a vote on whether Britain should remain in the union. Some 33% said they would cast their ballot in favour of a full withdrawal - including two thirds of Ukip supporters, 27% of Tories, 25% of Labour voters, and 17% of Liberal Democrats. However, more people - 42% said they were against leaving the EU. There were also signs that opposition to the union has softened, with the proportion who think there should be a referendum dropping from 68% in October 2011. At that time 37% wanted to exit the EU altogether.
