You would think that after the last few days broadcasters would consider Kelvin MacKenzie to be damaged goods, or, as I prefer to think of him, toxic. However, it's still possible that producers at Sky & the BBC cretinously think his presence on discussions & newspaper reviews will somehow add to the sum of our collective knowledge (when we already know that MacKenzie is a proven liar).
Sky may well be beyond the pale when it comes to MacKenzie (the Murdoch links are still there). That said, it is possible to contact the BBC & let it be known that you don't want part of your licence fee going towards any more appearance fees for him.
