The planned 24-hour strike by drivers on London Underground lines from Wednesday evening has been suspended.

Following successful talks at the conciliation service Acas, strikes on the Piccadilly and Hammersmith & City Lines will not go ahead.

Members of the Rail, Maritime and Transport union on the Piccadilly and Hammersmith & City Lines were due to walk out at 9.30pm on Wednesday December 7.

However, the union said all objectives in the Piccadilly Line dispute have now been achieved, adding it was committed to further talks aimed at a long-term agreement on the Hammersmith and City Line.

General Secretary of the National Union of Rail, Maritime and Transport Workers Mick Cash, said: “Talks with London Underground have proved to be positive and focused and as a result we have been able to make enough significant progress to allow us to suspend the strike action in both disputes that was scheduled for tomorrow evening.

"There is no question that the advances we have made have been down to the strength and resilience of our members in the workplace backed up by a determined and professional negotiating team.

"The solidarity that led to the resounding ballots for action has been absolutely decisive.”

Mayor of London Sadiq Khan said he welcomed the decision by the RMT and said negotiations can continue without “unnecessary disruption” for commuters.

Mr Khan said: "Nobody wins from strikes on the Underground. Commuters, businesses, TfL staff and Londoners all suffer. It's a lose-lose situation.

"As Londoners would expect, we are doing everything possible to encourage talks and repair the terrible industrial relations legacy of the previous administration."
