The Tories are on course to win about 30 seats in Labour‘s English heartlands on December 12 thanks to a dramatic swing against Mr Corbyn‘s party since the 2017 election, according to a Daily Mail poll.

It means the Conservatives are poised to triumph in working-class seats they have rarely – if ever – held, such as Bishop Auckland, Great Grimsby, Rother Valley, Stoke-on-Trent North, Workington and Bassetlaw. All are in areas which voted to leave the EU.
