This lack of interest in politics is confusing, because one of her friends had described her as a "very political person". And yet, when pressed, she will only declare an interest in - I'm not making this up - the Puppy Protection League. ("Well, somebody's got to look after puppies, because they certainly can't look after themselves.") Meanwhile, one person tells me she's "quite rightwing"; another that she's "definitely a liberal". How can we be sure which of them is right? "She said that she used to support herself with a foolproof system for betting on horses - but then that could be myth-making," says one friend. "I suspect her love life is pretty complicated, while she likes to give the impression of being chaste," says another.
