Parliamentary Voting System and Constituencies Bill

I would like to bring to my right hon. Friend's attention a particular difficulty in Wales that may be relevant. On the day that the referendum is taking place, a Welsh Assembly election is also taking place, the vote for which will use yet another different system. I wonder whether he has a view on whether we are confusing people even further, and in particular the Electoral Commission, by suggesting that it needs to explain that the subject of the referendum is a different system from that being used when people cast their votes on the same day.
