I will freely admit that I've just seen a tweet that said that Greta Thunberg, Lady Hale and Grayson Perry have just been announced as Today guest editors over the Christmas period and assumed it was a joke, a bit of satire. But, on Googling around, no, it really isn't. And there's also going to be George the Poet, exploring identity. Oh, and for balance!, Charles Moore of the Spectator/Telegraph. Who needs satirists anymore?
