The scale of Labour's crisis was laid bare today as a megapoll found Nigel Farage on track for Downing Street.

Reform would make the biggest surge in British political history if an election was held now, according to the YouGov research.

Although the party would be slightly short of an overall majority with 311 MPs, that would almost certainly see Mr Farage become PM.

Meanwhile, Labour would lose more than 250 seats on its current tally - and the Tories would slump into fourth behind the Lib Dems, with just 45 MPs.

The huge survey used a technique known as MRP to project results for all constituencies, based on the characteristics of their voters.

It found Yvette Cooper, Wes Streeting, Angela Rayner, Ed Miliband, Bridget Phillipson, and Lisa Nandy face being among the big-name casualties.

For the Conservatives it would be their worst result ever, stretching back to the formation of the predecessor Tory Party in the 1670s.

Robert Jenrick, Priti Patel, James Cleverly and Mel Stride are seen as losing their seats in the meltdown.

Reform's net gain of 306 seats would be easily the biggest increase for a party between two general elections.

Technically 326 MPs are needed for an overall majority - but with the Speaker and Sinn Fein MPs not participating in votes the real bar is lower.

The YouGov findings are based on national vote shares of 27 per cent for Reform, 21 per cent for Labour, 17 per cent for the Tories, and 15 per cent for the Lib Dems.

The Greens were on 11 per cent, the SNP on 3 per cent and Plaid 1 per cent.

However, some other polls have shown an even bigger advantage for Reform.
