J K Rowling's grasp of the English language has always been tenuous at best.

And now she has demonstrated her limited abilities on national television.

Yesterday morning we were treated to a fawning interview of her by the staggeringly ugly Will Gompertz, the BBC's arts correspondent, to mark the publication of her first adult book.

During the interview the gruesome Gompertz asked her if she would ever do another Harry Potter book. She replied that she might do a "director's cut" of a couple of them. Well, you silly woman, an original book is already a director's cut ipso facto, because the director (i.e. the author) wrote it in the first place.

I will not be rushing out to buy a copy of "The Casual Vacancy" because her standard of English is so poor that it would only make my hypertension even worse that it is now.

And speaking of making my hypertension worse; I would ask the BBC to not show the slimy Will Gompertz in any item on early morning TV as he makes my teeth curl up and stand on edge. Having Susanna Reid's eyes staring at me from her end of the Breakfast TV sofa is quite bad enough without my mouth feeling like it is chewing on a lemon too. Keep Gompertz on voice over duties ONLY please.
