London Underground bosses are to press ahead with their controversial plan to close ticket offices even though talks with the unions have failed to secure a deal.
London Underground Managing Director Mike Brown told the London Assembly Transport Committee the closures would start at the end of the year.
Tube workers have staged two strikes in response to the proposal to axe ticket offices at 256 stations with the loss of 950 jobs.
Mr Brown said talks with the unions were continuing but so was the closure plan.
London Underground says no staff will be made redundant against their wishes and 200 new jobs will be created with the arrival of night tubes next year.
London Assembly Green Party member Darren Johnson called on LU to carry out a trial scheme before pushing ahead with the full closure plan.
Mike Brown said managers already had experience of stations without ticket offices. He also ruled out a public consultation.
