In-fighting broke out almost immediately after the results were announced, with Diane Abbott saying it was "not possible to blame Jeremy Corbyn for this result" adding: "Keir Starmer must think again about his strategy." John McDonnell, the former shadow chancellor, told Radio 4's Today programme the party's candidate Paul Williams had been sent to the electorate "almost naked" and "policy-less". Lloyd Russell-Moyle, a former shadow minister, attacked the "valueless flag waving and suit wearing" the leadership had adopted in recent months. Steve Reed, shadow secretary for communities and local government, said the party should accept the results "with great humility", but insisted Sir Keir was the man for the job. A Labour source said Sir Keir would "take responsibility for these results" and for "fixing" the party's electoral woes.
