A majority of Britons who have made up their minds would vote for the United Kingdom to leave the European Union, according to a new poll.
An ORB opinion poll found that while 21 per cent of voters were still undecided, 43 per cent want to leave the EU, against just 36 per cent who want to remain in the 28-member bloc.
But when undecided voters were stripped out, the percentage of voters who want to leave the EU rose to 54 per cent, against 46 per cent who want to stay.
This compares with a poll conducted a year ago, where 51 per cent of voters wanted a Brexit, against 49 per cent who wanted the UK to remain in the EU.
The poll will put pressure on Prime Minister David Cameron to secure his demands for reform from other European nations ahead of the promised In/Out referendum, to be held before the end of 2017.
Cameron is in Germany today, where he will be seeking support for his reform agenda. The Prime Minister is hoping to reach an EU-wide agreement at a summit next month.
Earlier this week the Prime Minister announced he will allow ministers in his cabinet to campaign with their conscience in the run-up to the referendum.
The ORB poll comes after a YouGov survey for The Times found 28 per cent of Ukip supporters want to stay in the EU.
When excluding those who don't yet know how they will vote, YouGov also found 51 per cent of voters wanting to remain in the EU, against 49 per cent who want to leave.
