While I am conscious that an issue can arise if different referenda on the Constitution are held on the same day, I would not like to close this off. Odd issues arise which can easily be dealt with on election day such as a bye-election in one constituency that might take place on the same day. It is a question of trying to get people out to vote and encouraging activity. There is also a cost efficiency element, not that I would be driven by that purpose. Flexibility must be maintained in the system with regard to unforeseen polls or urgent referenda. I can remember being confused on one occasion when I voted in several referenda on the same day. I was not sure what I was doing in the polling station, from which there is a lesson to be learned.
