LONDON (Reuters) - Britain may vote for a 12-point lead in the European Union if it holds another referendum, a poll by the public opinion firm Yogov showed today, the highest rate since the 2016 thunderstorm.

The poll, conducted on Wednesday by the People's Vote campaign calling for another referendum, showed 56 percent would vote for the EU and 44 percent would vote for it by excluding those who abstained or not.

"Support for remaining within the bloc by 12 percent is the highest so far," the campaign quoted Peter Kellner, the former chairman of the Yogov Foundation as saying.

In the June 23, 2016 referendum, 17.4 million Britons (51.9 percent) supported exit from the European Union, while 16.1 million (48.1 percent) refused to stay.

Yogov's poll showed that 48 percent would vote for staying within the bloc, 38 percent would choose to leave, and 6 percent would abstain. Seven percent said they did not decide. The poll included 1,070 people.

The poll showed that 78% of supporters of the opposition Labor Party supported the holding of another referendum.
