European Union Poll: Public Split On British Membership

Prime Minister David Cameron makes a speech on Europe, in central London, where he promised an in/out referendum on the UK's membership of the European Union by the end of 2017, if the Conservatives win the next general election.

British people are equally divided on whether or not the United Kingdom should remain part of the European Union, according to a poll published on Tuesday. The YouGov survey showed 39% of those asked would vote to stay in the EU and 39% would vote to leave.

Of the three main parties Conservative supporters are the most eurosceptic with 47% opting for withdrawal compared with 32% who would choose to stay.

Labour voters would prefer to remain inside the EU by 55% to 26% and an overwhelming majority of Lib Dems, 71% to 21%, would like Britain to remain in the union.

Understandably 88% of Ukip supporters would vote for Britain to exit the EU. A small, if still surprising, 6% of Ukip backers would vote to stay in.

The poll comes as the Conservative Party pilots its EU Referendum Bill through the Commons. The legislation would commit the next government to holding an in/out referendum by 2017.

David Cameron has said he aims to renegotiate a looser relationship with Brussels before putting Britain's membership to a public vote.

Asked whether they would want to remain part of the EU under the new terms negotiated by the prime minister, 52% said they would while 28% said they would still want to leave.
