Sadiq Khan accused the Tories of an “abject failure” to tackle the housing crisis as he launched his mayoral campaign with a pledge to build 40,000 new council homes by the end of the decade.

In a speech on Monday alongside Sir Keir Starmer, he said London would go “much further, much faster” with Labour running both Downing Street and City Hall.

Mr Khan promised to unleash “the greatest council housebuilding drive in a generation” and to double his previous goal to start building 20,000 council homes, which he hit last year.
