Parliamentary Voting System and Constituencies Bill

I am listening carefully to the hon. Gentleman's argument. He clearly concedes that the electoral arrangements and voting systems which may change in future will apply to Scotland, Wales and Northern Ireland. Will he also concede that there is a precedent for the Government's legislation? In 1998 there was a referendum on future constitutional arrangements and the establishment of the greater London Authority and the Mayor, at the same time as the holding of 32 separate London borough elections.
