Sir Keir Starmer should resign as Labour leader if the party finishes third in the upcoming Gorton and Denton by-election, a prominent trade union leader has said.
Maryam Eslamdoust, general secretary of the Transport Salaried Staffs’ Association (TSSA), has publicly backed Angela Rayner to replace him, marking the first time a leader of one of Labour’s affiliated unions has openly supported an alternative to Sir Keir.
