Diane Abbott has accused Keir Starmer of trying to 'humiliate' her as part of efforts to 'clear out' the Left from Labour. The veteran MP, a close ally of former party leader Jeremy Corbyn, hit out at the Prime Minister and claimed he treated her as a 'non-person'. In a fresh round of Labour infighting, Ms Abbott, 70, issued a blast at Sir Keir's behaviour during a row over racist comments made about her by a Tory donor.
