European Union Bill

On the Minister's previous point, may I gently suggest that the difference between the alternative vote system and first past the post is that the candidate should receive more than 50% of the vote? So, there is a difference, even if only one candidate is listed. On clause 19, what does he estimate the cost to be of a referendum on any of the Bill's measures that would trigger a referendum? Given the Government's slightly confusing messages—they promise not to transfer power to the European Union, as set out in the coalition document, yet they demonstrate their eagerness through the Bill to commit to a referendum when a trigger is in place—will he estimate how many referendums we will have in this Parliament and, therefore, how much of a drain they will be on the Consolidated Fund?
