Sir - I was interested to read your report of Robin Walker and his colleagues that Scotland's separation from the U.K. would be in neither party's interest (August 8th), - a view with which I agree. There is a surely however a question as to who is being allowed to vote on September 18.

My wife was born in Scotland to a Scottish father and an English mother, which makes her Scottish. If, as David Cameron and Alex Salmond tell us the question is a matter for the people of Scotland, why is she unable to vote?

Separately, I understood that The Act of Union was a solemn and binding agreement freely entered into by two sovereign nations. This being so, why are the people of the rest of the U.K. not being allowed to express their view?

Yours, in some puzzlement,

Martin Harris
