RMT general secretary Eddie Dempsey hinted at more Tube strikes today following a “total collapse” of industrial relations in London.

London Underground workers are striking all week after rejecting a 3.4 per cent pay rise and Transport for London’s (TfL) refusal to reduce their weekly working hours from 35 to 32.

Speaking alongside striking members at the TUC conference in Brighton, he suggested that TfL fat cats are overruling London Mayor Sadiq Khan in the dispute.

He warned that RMT will next consider industrial action over recently disclosed plans to close all ticket offices on the Elizabeth Line, which was reprivatised last year despite Labour’s election pledge for the biggest wave of public service insourcing in a generation.

“I want to know who is in charge in London — is it the Labour mayor delivering the promises in the Labour manifesto, or the permanent bureaucracy in TfL running riot?” he said.
