Sir Keir Starmer will seek to justify his new crackdown on the use of social media by teenagers in a speech on Monday morning, arguing that reform is needed to keep children safe in an era of ever-increasing smartphone use.
The prime minister is keen to cement his policy legacy as speculation mounts that he could soon be deposed as prime minister by Andy Burnham, who hopes to win a by-election this Thursday and return to Westminster to challenge for the Labour leadership.
As part of that push, Starmer had wanted to finalise a long-awaited “defence investment plan” earlier this week, but that plan was blown up by the resignation of John Healey. The defence secretary quit after failing to secure the funding he wanted for the plan.
