A 50 hour strike by tube workers will go ahead on Monday after last ditch talks to avert the action broke down.
Workers on the Waterloo and City Line will walk out from 9pm on Monday in a row over pay grades. The line is used by 35,000 commuters every day.
London Underground bosses claim that only three people voted for the strike action out of six RMT members in the control room at Waterloo - and said they were confident disruption to passengers would be avoided. Train drivers will not be involved in the strike.
The RMT said the strike was due to tube bosses 'turning down any form of arbitration' and refusing to make a new offer on pay.
