Whatever your view of Miriam Margolyes (I think she’s fabulous), you cannot deny that she comes with a guarantee: she is biologically incapable of being dull.

Who did not savour the queasy look on Alan Yentob’s face when she asked him sweetly: “How old were you when you had your first f***?” “Er, probably about f-fifteen,” Alan mumbled, adding: “I’m not sure we can leave this in.”

They did leave it in, happily. To chop it would have been a travesty. I loved the superb timing of her anecdote on The Graham Norton Show
