According the the union, Unite, London Underground faces the prospect of a complete shut down this Bank Holiday weekend as workers, who control the power to run the trains, prepare to strike.
Unite regional officer Hugh Roberts said:
"There is a real possibility that the underground could close down over the bank holiday weekend. Unite is working very hard to achieve a fair settlement for our members - and to avoid the industrial action. The ball is very much in the management's court."
