It's very interesting to me that the nationalist movement in Scotland has become so positive and self-reflective rather than anti-English. The referendum in 2014 was peaceful, for all its deeply and passionately divided people.

You think back and you ask yourself why you became so interested in wolves. I think it was because when I was very small, growing up in a little hamlet near Shap, we would go to Lowther Wildlife Park for birthday parties. Now closed, it was only three miles from my parents' house.

We all have our preferences - some people go for birds - but for me, there's just something about the wolf; the design of it is really aesthetically pleasing.
