Government of Wales Bill

My hon. Friend rightly said that referendums have become one of the accepted mechanisms whereby people are asked whether they want more powers or fewer powers to be given to this or that body. Does he, in the same context, accept, on the same basis, that referendums can, and occasionally should, be used to ask people whether they want the body to exist at all? In other words, a referendum can be used to give, but on occasion also be used to take away.
