A strike planned to start on the London Underground on Wednesday, July 8, and carry over to July 9, is looking increasingly likely, although talks are ongoing.

The industrial action is expected to be the worst for more than 10 years as all four unions representing Tube workers, including Aslef and the RMT will stage a walkout.

Negotiations over the night Tube service between workers and TfL broke down over the weekend.

Unless fresh last-minute talks between the transport authority and the unions are successful, the strike is expected to be the worst since 2002 when the entire network was closed by industrial action.

A total of 11 lines and 260 stations are set to be affected.

Major strikes in recent years involved mainly RMT and TSSA unions, which represent station staff, but Aslef, which represents around 3,500 drivers, is also set to come out.

RMT, Unite and TSSA members will walk out from 6.30pm on Wednesday, July 8, with Aslef drivers joining the action at 9.30pm.

The TfL website will offer advice on travelling in London during the strike.
