A Conservative minister has said Labour is heading towards “the largest majority this country has ever seen”.

Work and Pensions Secretary Mel Stride not only appeared to concede the election to Labour a day before voting begins but said they would gain a record number of seats.

He told Sky News: “It appears, if the polls are right, that we’re heading towards the largest majority that this country has ever seen, much greater than even 1997’s landslide.”

Mr Stride was talking after other leading Conservatives, including Rishi Sunak, David Cameron and Boris Johnson, have warned of Labour gaining so many seats it would have a “supermajority”.

A Survation MRP poll released on Tuesday put Labour on course for a landslide victory, winning 484 of the 650 seats up for grabs, many more than the 418 won by Tony Blair in 1997.

It predicted the Conservatives would win just 64 seats - the fewest since the party was founded in 1834.
