Talks to avert a walkout by the london Underground staff have failed without a resolution and a strike is expected cause travel chaos for millions.
The failure happened on Saturday between the company and officials from the Rail, Maritime and Transport (RMT) union and the Transport Salaried Staff Association (TSSA), the Guardian reported.
Although the 24-hour stoppage is set to start on Sunday, disruption will run through the following day, Xinhua news agency reported.
Most tube stations in central london and many interchange underground stations will be closed during the stoppage. The dispute is over plans to cut station jobs and close station ticket offices.
But in a message to members of the transport union, RMT regional organiser John leach said the talks had failed and the strike by his union would go ahead.
