Keir Starmer will declare on Monday that Labour has changed “permanently” under his stewardship, after the party ruled out raising income tax or national insurance if it wins the election.

In his first keynote speech of the general election campaign, the Labour leader will seek to reassure nervous voters that transforming his party has been his “driving mission since day one”.
