Nigella Lawson has been accused of lying in court about the extent of her drug use.

Her former personal assistant Elisabetta Grillo told Isleworth Crown Court she believed the celebrity chef habitually used class A and B drugs.

Ms Grillo and sister Francesca are on trial for fraud - which they both deny.
