Tube strike latest: TfL warns passengers of four-day shutdown next week if RMT action goes ahead.

Commuters face a four-day Tube shutdown next week if a union presses ahead with threatened strike action, The Standard has learned. Talks are due to be held on Tuesday between Transport for London and the RMT union in a bid to avert what would be one of the worst strikes in years. The RMT has ordered its members to take part in a “rolling” strike - with different staff walking out at different times - as part of a battle to win a reduced working week in addition to an offered 3.4 per cent pay rise. Transport for London expects “little to no service” on the London Underground between Monday and Thursday next week, September 8 to 11. The dispute has already resulted in Coldplay moving the dates of two of their 10 concerts at Wembley Stadium – from Sunday September 7 to Saturday September 6, and from Monday September 8 to Friday September 12 – to the dismay of many fans. But the revelation that the Underground faces a virtual four-day shutdown will heap pressure on London mayor Sir Sadiq Khan, who chairs the TfL board, to intervene.
