This LRB review of the latest Thatcher biography reminded me of a very true thing Ian McEwan wrote after her death in 2013. "It was never enough to dislike her. We liked disliking her."
In that spirit, this programme - A Very Welsh Coup - from BBC Wales is well worth a listen. It tells the story of her removal from Number 10 through the slightly shoe-horned fact that Geoffrey Howe and Michael Heseltine are both surprisingly Welsh.
