Nearly all referendums ask whether voters support a particular piece of legislation or a proposition. It is highly unusual for them to be asked to vote on a whether they support bits of a bill.
Given the AV referendum was shoe-horned into a bill reducing the number of parliamentary constituencies, shouldn't we have been asked to vote on this question yesterday?
Do you support the introduction of the Parliamentary Voting System and Constituencies Bill that reduces the number of MPs and introduces the alternative vote system for electing them?
Just a thought.
