The Conservatives inflicted a historic byelection defeat on Labour and regained the Tees Valley mayoralty by a landslide as Keir Starmer conceded his party had lost the trust of working people across England.

The Labour leader, who called the local election results bitterly disappointing", is considering moving his party's headquarters out of London to reflect Labour's determination to show that it represents the whole country, party sources told the Guardian.
