Talks aimed at averting more strikes by London Underground workers have adjourned until Monday.
Officials from the RMT and TSSA unions met London Underground (LU) managers under the chairmanship of the conciliation service Acas to try to resolve a row over ticket office closures.
Union members staged a 48-hour walkout which ended last night after causing travel chaos in the capital.
Another 48-hour strike is planned from next Tuesday evening unless a deal can be agreed.
An Acas spokesman said: "Talks took place at Acas today and the parties have adjourned to consider their positions. All parties have agreed to continue with further discussions on Monday."
RMT leader Bob Crow said: "Talks involving all parties at Acas have concluded for the night.
"We will return to the issues on Monday and the strike action scheduled for Tuesday remains on.
"RMT will be issuing no further statements before Monday."
