A union representing over 400 Tube workers has suspended two 24-hour walkouts planned for this week  as a "goodwill gesture", it has said. 

London Underground (LU) workers were due to strike today (August 24) from 6.30pm and for a further 24 hours from 6.30pm on Thursday (August 27). 

The industrial action is part of an ongoing row over the introduction of the Night Tube, scheduled to start on September 12. 

Electrical and maintenance technicians, linesman and signallers from Britain's largest union, Unite, and LU workers for the RMT and TSSA could still strike next month on September 8 and 10 if a deal is not reached. 

Aslef had already confirmed earlier this month that its drivers were not taking part in the two 24-hour walkouts. 

Talks with conciliation service Acas continued until yesterday evening where enough progress was made to halt the action. 

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."

Transport for London (TfL) said "LU remains operationally ready to start the Night Tube on September 12".

Managing director for LU, Mike Brown, added: "It is good news for London that the strike has been suspended. 

"We will now continue to work with the unions, so that we can resolve this dispute and get on with delivering for our customers, businesses and London."
