A proposed three-day strike by London Underground staff has been called off by the unions.

The 72-hour strike was due to start from 18:30 on Sunday, but unions said they have now received guarantees on many of the safety and staffing issues from London Underground, including a halt to station closures.

According to the Rail Maritime and Transport Union, LU has dropped its plan to retain the use of agency staff and mobile station supervisors' and frozen plans to close or reduce opening times of ticket offices.

It has also pledged to ensure that all station staff are directly employed and fully trained to LUL safety standards.

"Our members have blocked changes that would have undermined the Tube's excellent safety standards, and despite the usual media vilification I hope Tube users will recognise that we have successfully defended their safety," RMT general secretary Bob Crow said.

The strike would have meant chaos this weekend with thousands of football fans leaving Wembley Stadium after the FA Cup semi final clash between Barnsley and Cardiff.
