If I'd been interviewed I'd have said something like this:
I was born in London, grew up in the South East and have spent the larger part of my life in Greater Manchester. I feel English but call myself British, the one being an identity of the heart, the other of the head. As far as I know (which isn't much) I have no roots in any other country. I like living on a multi-ethnic street. I think the Union as it stands is a good idea- and I'd prefer the Scots to stick around. Somewhere down the line I also think of myself as European.
