Charles Saatchi was funding a monthly household credit card bill of £100,000, which included paying for luxury holidays and designer clothes for his assistants, a court has heard.

Accountant Rahul Gajjar said Mr Saatchi's then wife Nigella Lawson spent around £7,000 a month, but Francesca and Elizabeth Grillo, the couple's personal assistants, spent an average of more than £75,000 per month.

He also told Isleworth Crown Court other assistants employed by Mr Saatchi spent a maximum of £8,000 a month.

The Grillo sisters both deny fraud.
