Sir Keir Starmer faces a test of his authority after vowing to discipline leaders who defied his orders and have joined the railway picket lines today.
At least four of his shadow team met with members of the RMT union, who are organizing three national outings this week. His own MP, Angela Rayner, backed the action on Twitter, undermining the Labor leader’s attempt to forge a compromise.
More than 50,000 RMT members have abandoned layoffs and wage increases below inflation, and the union general secretary has threatened to keep it up over the summer. London Underground staff are also on strike today.
Starmer was already at odds with his party’s left, with more than a dozen Labor MPs publicly supporting the strikes.
