Something wasn’t right. I was watching Celebrity SAS: Who Dares Wins (Channel 4, Sunday) and the deal was the same as ever: a gaggle of reality TV faces, athletes, actors and assorted coat-tail travellers are shipped to the middle of nowhere to be put through hell by ex-special forces soldiers while the viewers sit cosy at home, snickering. Only this time one of the “slebs” was bothering me. It was Rachel Johnson, journalist and brother of you know who, and it was not for the reasons you might think.
