What do you mean summer? Thatcher and The Queen disliked eachother immensely.
Well, Thatcher challenged the old established class system, which indirectly challenged monarchy. I've heard that QEII and family mocked Thatcher in private, but I've never heard the queen publicly voice complaint against Thatcher. She seemed quite supportive of Thatcher's Falklands war and didn't seem to have a problem with Gulf War I. The queen's feelings about Blair seem to be uniquely hostile. And although always diplomatic, I got the feeling that she was slightly uncomfortable on this last visit to the US.
But I'm thousands of miles away from the UK and I don't usually follow British politics.....
