Rating: Rating: Chatting with Laurence Llewelyn-Bowen during an interview the other week, I smugly remarked that we'd painted our downstairs rooms in Farrow & Ball colours. 'Oh, well done you,' said Loz, his voice dripping like a paintbrush with sarcasm. 'You've ruined your house. Aren't you clever?' Laurence was not invited to contribute to Farrow & Ball: Inside The Posh Paint Factory (C5). That's no shock but it is a pity, because his ruthless judgments would have punctured the show's pretensions. Instead, we got an extended advert for the Dorset company that has just been sold to a Danish outfit for just over half a billion quid.
