I guess that David Starkey must be planning to give up doing any history that might involve him coming in close contact with the Queen in the future. This morning he has compared her to Goebbels in the Guardian and essentially calls her a thicko philistine.
Now, it may very well be true that Madge is a shameful lover of low popular culture rather than high art, and frankly I quite like the idea of that more than being stuck up one's own arse in artistic and cultural snobbery like Starkey evidently is.
However, if you're going to be a Royal historian it's probably not a very good idea to compare the current Monarch to a Nazi and suggest she's thick. Not exactly going to keep those doors opening for you is it?
