Term Limits from 2008?

After the House of Lords this week voted to impose a two term limit on a Mayor of London (and Assembly Members!), Sally Hamwee is introducing an amendment in the House of Lords next week to ensure that the term limits do not apply until after the London Mayor and Assembly elections next year.
Sally Hamwee said: "There are quite distinct views on the principle: That an individual with such considerable executive power should be limited in how long he can serve. Or that it is entirely a matter for the electorate, once every four years. The vote, at any rate so far as the Lib Dems were concerned, was not a personal attack on Mr Livingstone - during the debate I said that if Graham Tope were Mayor I'd still be supporting the limit, and I'd expect him to do so if I were. The amendment won't stick; the Tories on the Assembly echoed their Commons colleagues (a split between Tories in the two Houses?) and lined up to say they thought Mr Livingstone was quite right to fight the restriction." Graham Tope moved the issue during the Lords’ debat, as well as fighting for greater powers for the London Assembly to challenge the Mayor’s budget.
