London Underground workers have announced further strike action over the ongoing row about the introduction of the night Tube.

Members of the Aslef union, which represents around 80 per cent of Tube drivers, will go on strike for 24 hours from 9.30pm on August 5.

The industrial action follows a 24-hour walkout last Thursday, July 9, over a row about pay and conditions when the night Tube starts in September.

Union representatives will meet for talks with London Underground management at conciliation service Acas tomorrow.
