Strike action planned by London Underground train drivers is set to be suspended after progress was reportedly made in talks over the Night Tube service.
Aslef, the union which represnts train drivers, is allegedly set to recommend suspending the three 24 hour walkouts proposed.
The first strike was due to take place next week, with two more in mid-February.
Aslef said good progress had been made in talks with London Underground bosses at conciliation service Acas.
Finn Brennan, the union's lead organiser, said: "I am pleased to say that we have made good progress in talks at Acas today.
"The negotiating team is now reporting to the Aslef executive committee with a recommendation that the planned industrial action be suspended.
"The determination of our members brought London Underground management back to the table.
"We have dragged them kicking and screaming into the 21st century with an agreement to deliver modern, flexible working patterns for our members and an above inflation pay rise.
"This demonstrates just what strong, progressive trade unions can deliver in Britain today."
The two other unions due to take part in strike action - TSSA and the Rail, Maritime and Transport union - said they had not yet reached a decision on whether to suspend industrial action.
Manuel Cortes, TSSA general secretary, said: "Following talks at Acas with London Underground today, TSSA negotiators will meet with our union representatives tomorrow to discuss the offer now on the table.
"No decision on whether or not to suspend industrial action on the Tube next week will be taken until after that meeting."
A spokesman for the RMT union said the revised proposals presented by London Underground bosses would be "considered in detail" by the union's executive tomorrow through its normal democratic procedures.
