Charles Saatchi is due in court in London to testify in the fraud trial of two sisters who worked for his ex-wife Nigella Lawson.
Elisabetta and Francesca Grillo deny embezzling almost 700 thousand pounds to fund a lavish lifestyle.
Mr Saatchi and Ms Lawson are being accused of using the case 'as a forum for backbiting.'
