Diary: In TV land, every London adman is a millionaire

Just because someone from London moves up North, it doesn't mean they are richer than their Northern compatriots.

But that's what the producers of The Secret Millionaire must have thought when tempting philanthropists on to their next series.

The TV programme, which has undercover millionaires living or working in deprived areas before handing out their cash to the most deserving, recently approached Robert Harewood-Matthews, the Cockney barrow boy and chief executive of TBWA\Manchester, to be on the show under the impression that he's a millionaire.

Since heading North two years ago, he's caused a bit of a stir with his Southern ways. However, just because he hails from London doesn't make him a millionaire. He isn't. The producers on the show should be ashamed.
