British Prime Minister Keir Starmer marks a year in office this week, facing challenges from within his party and the public.

British Prime Minister Keir Starmer won a vote on his welfare plans on Tuesday at significant political cost as he suffered the biggest parliamentary rebellion of his premiership and was forced to back down on key parts of the package.

Amid fears of imminent defeat, Starmer authorised a last-minute climbdown. Experts said the emasculated bill, which passed a parliamentary vote on Tuesday evening, could even lose the government money overall after it was initially intended to generate net savings of £5bn.

Sir Keir Starmer has admitted he "did not engage" properly with Labour MPs, leading to a series of damaging U-turns on his flagship welfare reforms. On Tuesday, the government avoided defeat on its proposals to overhaul disability benefits by offering late concessions to Labour MPs threatening to rebel.

The question is not whether the passing of Starmer’s new welfare bill has caused damage to the government, but how much?
