Union bosses have called off two 24-hour Tube strikes, which were set to take place over four days this week.

Leaders from the RMT, Unite and TSSA agreed to suspend the strike action following last-ditch talks with London Underground bosses at Acas.

The underground was to be shut down on Wednesday (August 26) and Friday (August 28) as part of an ongoing row over the proposed Night Tube plans which has seen the underground grind to a halt twice since July.

But, on Monday afternoon (August 24), Unite, TSSA and the RMT announced they would not be going ahead with the strike action.

Aslef had previously said, due to previous strike action, it would not be involved in this week's planned walk-outs.

RMT general secretary Mick Cash said, in an online statement: "London Underground has been informed that ALL INDUSTRIAL ACTION IS SUSPENDED.

"This includes the two 24-hour strikes starting from tomorrow (Tuesday August 25) and all industrial action short of a strike including the overtime ban.

"All RMT members working for London Underground should report for work and undertake all duties as normal."

Unite regional officer Hugh Roberts said: "There are still some remaining sticking points, but we feel sufficient progress has been made to suspend industrial action as an act of goodwill.

"We will continue to approach talks with London Underground in a positive manner. We trust that London Underground management seize this opportunity to reach a deal that fully addresses our members’ concerns and secures a successful future for night running on the Tube."

And TSSA leader Manuel Cortes said: "I am extremely pleased to say that our negotiating team has made sufficient progress to suspend this week's planned strike action on the Tube.

"However, we are not out of the woods yet. A number of issues need to be resolved before our dispute is finally settled.

"We will therefore announce future strike dates in due course although we remain hopeful that further talks will soon result in a negotiated settlement."
