A former personal assistant accused of defrauding Charles Saatchi and Nigella Lawson has denied she is a shopaholic and a fantasist.

Francesca Grillo, 35, said she disagreed with how the TV cook had described her.

She and sister Elisabetta, 41, are alleged to have spent £685,000 on credit cards belonging to the couple.

Luisa Baldini reports from outside court.
