LONDON Underground workers will go on strike over an ongoing row about pay and the Night Tube.

The Rail, Maritime and Transport (RMT) union will stage three 24-hour walkouts on January 26, February 15 and February 17 over the introduction of the 24-hour Tube service.

Members will also take part in a week of industrial action, from February 7 to 13, over cuts to station staffing numbers, the union added.

The announcement came as the Aslef union decides whether to take part in the 24-hour strikes.

RMT general secretary Mick Cash said: “RMT members are furious at the bodged introduction of the Mayor’s Night Tube plans and the fact that they have been tied in with a pay deal that has left our members dangling on a string and out of pocket since April last year.

“RMT supports the principle of a properly worked out Night Tube service introduced through agreement with the unions but the abject failure to work through the detail has led to a comprehensive breakdown in the negotiations and has forced us to name a programme of further industrial action.

“This whole situation could have been avoided if London Underground, under direction from the Mayor, had dealt with the Night Tube professionally from the off instead of resorting to ultimatums and imposition.”

Mr Cash said the union remains “available for talks” in both disputes.

Mayor of London Boris Johnson said: "They were offered excellent terms and conditions for their members to deliver the Night Tube.

"They turned those down - without ever properly consulting their membership."

Strike action was taken by the unions last summer over the Night Tube, having called for increased pay and a limit on how many all-night shifts members would b e asked to do.

London Underground claims the 24-hour service is needed to deal with huge demand from passengers, especially at weekends, and would add £6.4bn to the London economy by 2030.
