Sir Keir Starmer reshuffled his shadow cabinet amid warnings from the hard-Left he would face a leadership challenge unless the party’s fortunes improved. Nick Brown, the chief whip, Anneliese Dodds, the shadow chancellor, and Valerie Vaz, the shadow Commons leader, were removed from their positions in the wake of the party’s disastrous performance in local elections. Their removals came as Sir Keir attempted to reassert his authority. Angela Rayner, the deputy leader, was removed as party chairman and national campaign co-ordinator on Saturday evening. Mrs Dodds and Mrs Rayner were given new positions as chairman of the party and shadow chancellor of the Duchy of Lancaster respectively. But Mr Brown and Mrs Vaz were removed from the shadow cabinet. On another day of recriminations and infighting in the party, Jeremy Corbyn’s allies turned on Sir Keir, saying he lacked “basic political skills” and vowing a renewed push against his modernising plans. Jon Trickett, the Labour MP and national campaign coordinator under Mr Corbyn, said: “If it comes to the questions of a leadership challenge, I don’t think we should rule it out.” John McDonnell, the former Labour shadow chancellor, vowed to fight Sir Keir’s modernising “in every branch, in every trade union [and] in every meeting at every conference”. Other prominent Left-wing MPs suggested Sir Keir’s plan for the party should be put to a confidence test and accused him of “baffling” decisions that were causing splits in the ranks The fierce opposition, as well as deputy leader Angela Rayner's refusal to accept a demotion in the reshuffle, left Sir Keir struggling to execute his planned shake up of the shadow cabinet on SUnday, fearing it could upset a delicate balance between the left and the party's moderates. The backlash to Hartlepool by-election defeat to the Conservatives and the loss of more than 300 English council seats played out across political TV shows on Sunday. Sir Keir had stripped Angela Rayner, Labour's deputy leader, of her roles as party chairman and national campaign coordinator on Saturday with a wider reshuffle planned for Sunday.
