Growing numbers of Londoners are swinging against Brexit with new polling revealing today that they would now vote by an overwhelming two to one to stay in the European Union.

The YouGov survey of nearly 2,400 Londoners found 66 per cent would support Remain if there was another referendum and 34 per cent Leave.

The findings contrast with the actual 60/40 referendum result in June 2016 in the capital and reveal a 20 point gap has widened to 32 per cent.

With recent nationwide polling showing a shift to Remain, the London results will fuel doubts over whether there is any longer a majority for Brexit in Britain.

They came amid widespread disillusionment over the Government’s handling of Brexit, with Theresa May struggling to salvage her Chequers plan on quitting the EU.

The swing against Leave in the capital is being driven by women, with 68 per cent now saying they would vote Remain, up from 60 per cent. One in 10 Londoners who voted Leave would now back Remain, with four per cent switching in the opposite direction.

The biggest generational shift appears to be among young adults, aged 18 to 24, with 87 per cent now saying they would vote to stay, up from 80 per cent. The analysis is a compilation of London samples from three nationwide YouGov tracker polls commissioned by the People’s Vote campaign.

Former YouGov president Peter Kellner said: “Londoners generally reject the promises made by Brexiteers two years ago. If London were a separate country, it would unquestionably want to be a member of the EU.” At least as many, if not a greater proportion, of Labour voters than Conservative supporters appear to be moving to Remain, 81 per cent in 2016 to 86 per cent now, piling more pressure on Jeremy Corbyn to support a second referendum, with fresh signs that he may be shifting towards it.

The survey found 52 per cent of Londoners support a public vote on the outcome of Brexit talks, with 30 per cent opposing it.

If there was a referendum, using a system similar to the London mayoral election, with three choices of remaining in the EU, quitting with the Chequers plan or leaving without a deal, Londoners would overwhelmingly back staying in. Sixty-four per cent would vote In with their “first preference” vote, the polling suggested, 13 per cent for Chequers, and 23 per cent to quit without a deal. Chancellor Philip Hammond indicated yesterday that Whitehall departments could be forced to cut spending programmes to help pay for the cost of a “no deal” Brexit, details of which are being worked on under plans codenamed “Operation Yellowhammer”.

At least two thirds of Londoners do not believe that it is likely that Britain will get a good Brexit deal, three quarters expect many of the promises made by Leave politicians will be broken, over half expect the economy to be weaker if Brexit goes ahead, with 15 per cent saying it will be stronger.

YouGov interviewed 2,379 Londoners between July 31 and September 3. Data are weighted
