RMT leader Bob Crow has revealed on live radio his "secret" plan to ambush Boris Johnson at City Hall. Crow plans to turn up uninvited at the Mayor's office with TSSA leader Manuel Cortes. The confrontation plan was hatched last night following the breakdown of peace talks at ACAS.
The confrontation came during the Mayor's monthly phone-in show on LBC 97.3 - thought to be only the second time the two men have spoken.
The dispute over ticket office closures was deadlocked tonight with millions of commuters almost certain to be caught in the crossfire.
London Underground says services will be affected from around 9:30pm on Tuesday 4 February.
