As Lord Rose (great name) being a known Eurosceptic, the fact that he's "Yes" should carry more weight than some.
The referendum campaign will be about swaying the undecided, which is quite a lot of people, not trying to convince people like (so it would seem) for example, us Answerbankers of one persuasion or another who will shout at each other in the name of debate for the next two years or so
I suggest a charity box for Bullsh*t referendum bingo:
"Snouts in the trough", "EUSSR", "get our country back"
"We must not be alone in the world" etc etc
