Wales Bill

I apologise for interrupting my noble friend once more and I promise that I will not do it again. Can she be clear about what the principle is? I take her point about consistency across the United Kingdom. Is the principle that 16 year-olds will be able to vote in referenda which are concerned with devolved bodies, or is it a principle that is to be generally applied to all referenda? In other words, would 16 year-olds have the vote, for example, in a referendum on our membership of the European Union, should that ever arise, or is it solely limited to devolved bodies?
