Rail union Aslef has confirmed that the Tube strike will go ahead this week after London Underground's latest deal was rejected.

The four unions involved – Unite, RMT, Aslef and TSSA – spent Monday, August 3, discussing the new deal from management for the Night Tube but it was dismissed by early afternoon.

Unite was the first to announce its members would walk out on Wednesday, August 5, and Thursday, August 6, before Aslef confirmed the wholesale action.

London Underground said the new package, worked up alongside conciliation service Acas, had no new money but attempted to 're-shape' the work-life balance of workers on the Night Tube, which is due to take effect from September 12.

Aslef said: "We would be prepared to continue discussions to try to find common ground, but senior management are insistent that new rosters will be issued this week so that Night Tube starts on September 12.

"The sensible option would be to postpone the launch date to allow for an agreed way forward to be reached. But once again, management are being completely inflexible and are refusing to negotiate on their offer. They are insisting that it must be accepted as it stands."

The distance between the unions’ and management position has already prompted the Mayor of London Boris Johnson to hint that the launch date might be delayed . On July 15 he said: “I can’t say exactly what date it is and I don’t particularly care but we’ll get it through this autumn.”

TfL said Tube services will stop running at 6.30pm on Wednesday, August 5. It urged people to complete journeys by this time and travel earlier if possible.

Tube services are expected to be "exceptionally busy" between 4.30pm and 6.30pm. DLR, London Overground, tram and overland TfL services would be running but would be busy.

There will be no Tube services all day on Thursday. Extra bus and river services will run, and all other public transport services and roads will be much busier than usual.
