London Underground drivers are to stage a 24-hour strike after voting in favour of industrial action in a dispute over working conditions.

Members of Aslef will walk out on October 5, threatening huge disruption for passengers and visitors to the capital.

The drivers voted by almost 9-1 to strike and a bigger margin for other forms of industrial action.

Finn Brennan, Aslef's organiser on London Underground, said LU had failed to deliver on commitments made to improve work-life balance as part of the 2015 pay settlement.

He said: "As part of the settlement of the dispute over the introduction of Night Tube, LU agreed to introduce a mechanism to allow drivers to reduce the number of shifts they work, on a pro-rata basis, and 'new ways of working' to reduce the percentage of weekend shifts worked by July this year.

"They have repeatedly refused to make any detailed proposals to do so. For more than 18 months, management have prevaricated, stalled and delayed.

"Deadlines have repeatedly been missed and promises broken while our detailed proposals to resolve these issues have been ignored."

How many people do Tube strikes affect and what do they cost the economy?
