The House of Lords has just accepted an amendment to the Greater London Authority Bill which would limit any mayor to two terms. Ken Livingstone reacted furiously in a statement to PA:
"It is up to Londoners, not Parliamentarians, to decide who is mayor. This is further evidence that David Cameron has no confidence in his party's candidates for mayor. They seem to have decided they can't win next year's mayoral election through fair means so now they have resorted to changing the law to prevent a fair choice.
In January they categorically opposed term limits for the London mayoralty, but within five months they have done a complete U-turn. I don't recall these parliamentarians ever calling for term limits for MPs. This is of course the second time that the Tory Party has sought to reject the ability of Londoners to decide who represents them - the first being Mrs Thatcher's abolition of the GLC.
It is up to Londoners to decide who represents them, not to have Westminster MPs overrule them."
My guess is that Labour will easily overturn the amendment in the Commons.
