Sir Keir Starmer has suffered the biggest blow to his leadership since coming into power a year ago after he was forced to abandon a key plank of his controversial benefit cuts in order to get them through parliament.
While his welfare reform bill passed its second reading by 335 votes to 260 – a majority of 75 – the prime minister still suffered the largest rebellion of his premiership so far, with 49 Labour MPs voting to reject the legislation.
