London Underground workers are to stage a new strike in a long-running dispute over jobs and pensions.
Members of the Rail, Maritime and Transport (RMT) union will remain out of work on August 19.
RMT members are also striking at Network Rail and 14 train operators on August 18 and 20 alongside members of the Transport Salaried Staff Association (TSSA) at a number of rail companies.
The RMT said the new Tube strike was prompted by Transport for London’s “refusal” to share details of a draft government proposal it received regarding funding for the capital’s transport system.
The union said it was giving TfL until August 2 to offer guarantees on jobs, pensions and working conditions.

RMT general secretary Mick Lynch said: “Our members will be picketing again in this important dispute over pensions, jobs and conditions.
“They have been screwed over by TfL and [London] Mayor Sadiq Khan. And to add insult to injury, they haven’t seen the detail of this government funding letter.
“Unless there are guarantees on jobs, pensions and damaging changes to working conditions, our strike on August 19 will go ahead.”
