More than a third of voters believe Britain may end up remaining in the European Union, according to polling.

Around one in five, 22 per cent, said they did not know if the UK would follow through with its Brexit vote, while 16 per cent are convinced the country will defy the result.

Nearly half the public, 48 per cent, want a general election before negotiations begin, so voters can give their verdict on each party's plans for life outside the EU.

Some 59 per cent of respondents were not confident the government will get the best deal for Britain, rising to 76 per cent of Remain voters, according to the Ipsos Mori poll for BBC Newsnight.

It found that five per cent of Leave voters would now change their vote compared with two per cent of Remain voters.

A total of 42 per cent, including 18 per cent of Leave voters, said Britain should continue to allow EU citizens to live and work in Britain in return for access to the single market.

Some 38%, however, said losing access to the single market would be a price worth paying for new curbs on immigration.

Ipsos Mori interviewed 1,077 people on Wednesday and Thursday.

A separate poll for the Evening Standard showed similar results - with more than half of respondents (52 per cent) backing a general election this year once the Tories have chosen a new leader.

The BMG Research survey of 1,016 UK adults also showed that the referendum result would be reversed if it were held today - with 45 per cent backing Remain and 40 per cent Leave - while 13 per cent of Leave voters said they regretted their decision.
