Where can you get live travel information during the strike? TfL says it is hard to predict where the worst delays will occur, but it has advised passengers to follow @TfLTravelAlerts, @TfLTrafficNews and @TfLBusAlerts on Twitter and check tfl.gov.uk before they travel.

Why is the strike happening?

Union leaders have staged a walkout over Boris Johnson's announcement that many ticket offices at Underground stations will be closed. It is expected that 950 jobs will be lost in the planned overhaul of the Tube network.

Bob Crow, general secretary of the National Union of Rail, Maritime and Transport Workers, said: "This comes at a time when the Tube network is under growing pressure from customer demand and needs more staff and not less to ensure safe and efficient operation.

"These cuts would hit the vulnerable, the elderly, those with disabilities and women the hardest. De-staffing stations, with supervisors running operations three stops down the line on an iPad would turn the Tube system into a criminals' paradise where those with violence and robbery on their minds are given a clear run.

"RMT will work with our sister unions and passenger groups to ensure that Tube users understand just what's at stake as Boris Johnson turns his opportunist election pledges on their head."
