If you're a London-based estate agent in the habit of wedging your diminutive frame, ginger hair and green eyes into a sports car while wearing Lacoste polo and slacks then we have some very, very bad news, viz. nobody likes or trusts you and it's time to buy a proper car, put on a suit and specs and become a doctor.

That, at least, are the conclusions of a survey carried out by Lewis PR, which set out to ascertain who are Britain's least trusted individuals.

Also significant among the findings is a dislike of people with beards and those favouring the Bobby Charlton-style "comb-over". Fair enough.

Cockey accents fared no better, with good, honest Yorkshire topping the regional linguistic credibility league table.

As for the battle of the sexes, Lewis declares it a draw, with women scoring just slightly better in the trustability index.

To summarise: your best bet of getting ahead in business is to be a Lexus-owning beardless brunette female GP with an athletic Yorkshire build and glasses. And no comb-over - that's a real no-no.
