Charles Saatchi mobbed outside court

Charles Saatchi has been greeted by a media scrum outside a London court as he arrived to give evidence in the trial of two of his former personal assistants, Francesca and Elisabetta Grillo.

The sisters, both of Bayswater, in west London, deny fraudulently spending more than £685,000 on credit cards belonging to the millionaire art dealer and his ex-wife Nigella Lawson.

The case has attracted huge media attention because of the sisters' allegation that Ms Lawson regularly took drugs.
