Eight out of the 11 Tube lines are running a limited service due to a 24-hour strike by workers which ends at 6pm today.

Transport for London (TfL) say around 60 per cent of stations are open across the network and are advising passengers that although the strike ends this evening the service may be disrupted throughout the day.

Members of the Rail, Maritime and Transport (RMT) union and the Transport Salaried Staffs Association (TSSA) walked out at 6pm yesterday and were said to be solidly supporting the action, as they mounted picket lines.

London Mayor Sadiq Khan said he “condemned” the “completely unnecessary” industrial action and called on the unions to return to the negotiating table.

RMT general secretary Mick Cash said: “This action has been forced on us by savage cuts to jobs that have reduced London Underground to an under-staffed death trap at a time of heightened security and safety alert.”

The union also accused LU of under-estimating the impact of the strike.

London Underground chief operating officer Steve Griffiths said: “This strike, called by the leadership of the RMT and TSSA unions, is unnecessary. We had always intended to review staffing levels and have had constructive discussions with the unions.”

TfL deployed “travel ambassadors” to help people get around the city and around 150 extra buses are deployed to enhance existing routes.

TfL is urging all customers to plan ahead and to check before they travel at tfl.gov.uk and by following @TfLTravelAlerts, @TfLTrafficNews and @TfLBusAlerts on Twitter.
