London's underground network faces a threat of disruption after union members approved strike action this afternoon.
Members of the Rail Maritime and Transport union (RMT) were balloted over a pay dispute, calling for the payment of a four per cent wage increase which had been due last April.
In total 2,271 RMT members approved the industrial action, with 705 opposing it. Approximately half of those eligible to vote did so.
RMT executives have already rejected a three-year settlement which London Underground (LU) have described as "very fair".
"A three-year pay deal on London Underground will be of huge benefit to staff and passengers alike," London's mayor, Ken Livingstone, commented.
"It will provide rising living standards for staff and good services to passengers."
Other unions have accepted the pay deal, but RMT executives will decide whether to name dates for strike action later today.
The RMT is also fighting to save 140 job cuts planned by the London underground network's cleaning contractors, ISS. It announced it would ballot ISS cleaners on Thursday.
