The Mayor of London has "wobbled" on controversial plans for the West London Tram.

Speaking on ITV last week Ken Livingstone said he may be prepared to ditch the unpopular scheme if a Brown-led government approves Crossrail.

Talking on the London Debate he said: "If we get Crossrail we will review whether or not we proceed with the tram."

Ealing, Hillingdon, and Hammersmith and Fulham, have all rallied against the plans.

Arguing against the 13-mile tram line the leader of Hammersmith and Fulham Council, Stephen Greenhalgh, said: "This is the first sign of a wobble from the Mayor on the Uxbridge Road tram.

"Until last week his blinkered approach meant that he was not prepared to listen to other transport solutions.

"This council, along with the vast majority of local residents, has been saying for years that the tram will cause misery for commuters by effectively closing down Uxbridge Road.

"At last it seems we may be starting to get through to him."

Conservatives in the London Assembly last week called for Gordon Brown to announce Crossrail as one of his first acts as Prime Minister.

Angie Bray, Conservative leader in the assembly and member for West Central, said: "London Assembly Conservatives demand that Gordon Brown's first act as prime minister should be to give the go-ahead to Crossrail.

"London has been waiting all these years for this vitally important infrastructure project and now it's time for him to show his mettle and nail his colours firmly to the Crossrail mast."

East-to-West rail service Crossrail, which would run from Maidenhead to Heathrow, has cross-party support in the House of Commons.

The trains would be able to carry 1,500 people and would provide a direct link to the city for residents in Heathrow, West Drayton, Hayes, Southall, Hanwell, West Ealing, Ealing Broadway and Acton.

The Crossrail Bill is now being considered by a select committee in the House of Commons.
