The tube strike that threatened to paralyse London for the second time in a week following the May Day protest has been called off less than four hours before it was due to start.
The RMT union decided not to go ahead with its industrial action after a letter from TUC leader John Monks imploring its members to go to work.
Talks between the union and the conciliation service ACAS broke down last night when the RMT board rejected a new deal with London Underground management.
But the union contacted London Underground after a further executive meeting today to say the strike had been cancelled.
The RMT was striking because it feared plans to run the tube using a public/private partnership would compromise safety.
