Scottish Labour leader Anas Sarwar has twice refused to back Keir Starmer over the sacking of a shadow minister who attended a picket line.
Sarwar said it was for Starmer to make decisions about his MPs but pointedly said he encouraged his MSPs to get on the frontline backing workers.
Sam Tarry was fired as a junior transport minister last week after he defied a ban on attending a picket by striking rail workers.
