More than half of Brits would vote to leave the EU

David Cameron has promised that if he remains Prime Minister after May’s general election he would renegotiate Britain’s membership of the EU before staging an in-out referendum by the end of 2017.

Recent opinion polls have suggested support for remaining in the EU, especially after reforms to its workings, was growing.

However, the Opinium survey shows more people would vote to leave in a referendum.

The poll also found that 41 per cent of people think that the EU is generally a good thing for the UK, while 34 per cent said it is generally a bad thing.
