Ever one to hop on a bandwagon, Tesco must have noticed all that valuable publicity for the Attorney General and her permit-free housekeeper.

It emerged this week that Gambian checkout girl Fatou Cham handpicked to front ads for the Florence & Fred clothing range was in the UK illegally. Oops. "We followed the correct procedures," straight-faced a spokesman, while Cham admitted her dream of till-based prosperity had gone "horribly wrong".

Sainsbury's should also beware tabloid revelations. King Justin's men are giving cooking advice to X Factor contestants two of whom The Sun last week described as a "sleazy stripper" and a "knife-wielding thug". At least one should be handy in the kitchen.
