The news everybody in London was dreading has come true: a 24-hour Tube strike is taking place after talks between Transport for London (TFL) and unions failed.

Major stations throughout London have been affected since 6pm GMT on Sunday (8 January) and will continue to be affected throughout all of Monday (9 January). TFL have said most Zone 1 stations will be closed during the strike action.

Why is there a Tube Strike?

The Rail, Maritime and Transport union (RMT) walked out of talks with Transport for London (TfL) at mediation service Acas collapsed on Sunday. The strike is part of long-running dispute over former Mayor of London Boris Johnson's Fit for Future Stations programme which saw 900 station staff jobs lost.

RMT general secretary Mick Cash blamed "savage cuts" for the industrial action and said the solution was in the hands of Labour Mayor of London Sadiq Khan.

TSSA general secretary Manuel Cortes said in a statement on Sunday: "Our reps have decided to go ahead with our 24-hour strike action at 6pm today. Whilst they accept the offer of more staff is a step in the right direction to restoring Tube safety standards, they do not believe the offer will return those standards with the urgency that is now needed. We remain committed to taking part in further talks to seek a resolution to this dispute."
