How the legal case built up against Nigella Lawson

20 December 2013 Last updated at 18:37 GMT

Nigella Lawson has said she is "disappointed but unsurprised" that two sisters who worked as her personal assistants have been cleared of fraud.

The trial of Francesca Grillo, 35, and sister Elisabetta, 41, heard they spent £685,000 on credit cards owned by the TV cook and ex-husband Charles Saatchi.

They claimed the TV cook allowed their spending to cover up her cocaine use.

Ms Lawson, 53, said her experience as a witness was "deeply disturbing" and she had been "maliciously vilified".

The BBC's Clive Coleman said the case has been unusual because evidence was released before the trial began.
