Talks are to take place with London Underground workers over the next few days in a bid to avert a three-day strike that could see travel chaos.

Tube workers last week voted in favour of a three-day strike in protest at safety on the Underground.

The walk-out is scheduled to start from 6.30pm on Sunday, April 6 to 6.30pm on Wednesday, April 9.

The Rail Maritime and Transport (RMT) union and Transport Salaried Staffs Association claim standards will be compromised if plans go ahead to close 40 ticket offices and cut opening hours.

Transport for London (TfL) insist the measures do not relate to safety and dismissed the need for industrial action.

Howard Collins, TfL's deputy chief operating officer, said: "All of the issues raised by the RMT are already being addressed through the normal negotiating process. Significant progress has already been made and most of the issues have been agreed."

A RMT spokesperson said it was hoped that talks this week would see a positive outcome and that they were still ongoing at this stage.

Travellers are set for 72 hours of misery if a deal cannot be reached.
