Exclusive: TSSA general secretary wants Rayner to take over after Gorton byelection which she expects party to lose

Maryam Eslamdoust, the general secretary of the Transport Salaried Staffs’ Association (TSSA), told the Guardian she wanted the former deputy prime minister to take charge after this month’s Gorton and Denton byelection.
