Users of the London Underground network can expect huge disruption as the Rail Maritime and Transport union announces new strikes later this month.

The union has confirmed that more than 10,000 workers across the Tubes will walk out on Tuesday, June 21.

They are set to coincide with the first day of the national rail strike which will see 50,000 workers strike across three days and mark the biggest national walkout since the late 1980's.

The strikes come over disputes of pensions and jobs losses and will follow the strikes that took place after the Platinum Jubilee Bank Hoilday weekend.

Back in March, a similar walkout took place that saw the entire London Underground network come to a standstill as workers strike. 

It saw more than 200 stations closed and commuters having to pack on buses and queue for Boris bikes to get home.

Major travel disruption was also seen on Monday (June 6) when 4,000 RMT Tube staff took part in industrial action.

RMT general secretary, Mick Lynch said: "TfL, London Underground Limited (LUL) and the Mayor of London have had ample opportunity to negotiate with the union properly to avert this strike action today.

"We will not rest until we have a just settlement to this dispute and we urge the Mayor to stand up to the Tory government who are cutting funding to TfL rather than try to pick a fight with tube workers."
