Exclusive: Letter signed by figures on right and left of party says UK should follow Australia’s example by enacting ban

More than 60 Labour MPs have written to Keir Starmer urging him to back a social media ban for under-16s, with peers due to vote on the issue this week.

The MPs, who include select committee chairs, former frontbenchers and MPs from the right and left of the party, are looking to put pressure on the prime minister as calls mount for the UK to follow Australia’s precedent.
