       More than 10,000 workers are eligible to strike, but the union is yet to confirm which groups of workers will strike on which days.

       Once we have an update, we will let you know.

       Why are the London Underground strikes taking place?

       The strike is part of a long-running row with TfL over job cuts, working conditions and pensions.

       The union said the cuts could lead to the loss of 600 jobs across the network.

       RMT general secretary Mick Lynch said: "This week of action will shut down the London Underground and show just how important the work of our members is.

       "Plans by TfL to cut 600 jobs and attack our members pensions are simply unacceptable.

       "We are aware that Mayor of London Sadiq Khan has had the TfL budget cut.

       "However, he needs to align himself with our union and his London Underground staff in pushing back against the Tory government, exposing their damaging agenda to a key part of London transport infrastructure."

       Glynn Barton, chief operating officer of TfL, said: “We are disappointed that the RMT has announced strike action on this range of issues that we have been attempting to discuss with them openly and co-operatively.

       “We are urging the union to reconsider and engage with us to discuss the issues and seek a resolution.”

       The Government transport agency has said that they have no current proposals to change its pension arrangements.

       However, it is exploring a range of proposals to ensure no employee will lose their job or work extra hours.
