My eldest son has had to live with being a bit of a Harry Potter look alike over the last few years. At the age of 11 he had girls screaming in the street at him. I think he's come to terms with it.
I now find he has more in common with JK Rowling than I realised. Last weekend we were discussing politics and I asked him why it so appealed to him. His answer was explicit: politics, he suggested, was about having power to change things. I laughed and told him he should tell Jeremy Corbyn (who he has met) that.
J K Rowling clearly agrees with him: in a series of tweets she has made clear that a Labout leader of a fan club but not of a parliamentary party is of no benefit to those who need an effective opposition and a government in waiting in this country.
I agree with them both.
