MPs have headed off for the summer holidays but despite the sunshine, clouds are looming for Jeremy Corbyn.

Over the weekend, a new poll found that Labour would have a clear lead over Boris Johnson if Mr Corbyn was replaced at the top of the party.

The Deltapoll survey for The Mail on Sunday placed the Tories on 30 per cent, with Labour on 25 per cent, and the Liberal Democrats on 18 per cent. Nigel Farage’s Brexit Party was losing ground on 14 per cent.
