Labour leader Sir Keir Starmer is facing a potential rebellion from his party after sacking Sam Tarry for attending a rail strike.
Mr Tarry, who is in a relationship with deputy party leader and Ashton-under-Lyne MP Angela Rayner, was fired from his senior role as shadow transport minister after he publicly backed the rail strikes by attending a picket line without permission from his party's headquarters. However, Sir Keir has faced a wave of backlash from both the unions and the left-wing of his own party for the move.
John McDonnell said in an interview with Sky News that it was a "severe mistake" while also accusing Sir Keir of "misreading the mood of the public". Officially, Labour does not publicly support the rail strikes, however, it has criticised the government while urging ministers to become involved in negotiations.
