Nigella Lawson 'will not face probe' over drug claims 21 December 2013 Last updated at 05:19 Television cook Nigella Lawson will not face an investigation over claims she took cocaine, police have said. Scotland Yard said it would not look into the allegations at this stage but would review the decision if new evidence came to light. Giving evidence at the trial of two former personal assistants, Ms Lawson said she had previously taken the drug. Sisters Francesca and Elisabetta Grillo were cleared of defrauding Ms Lawson and her former husband Charles Saatchi. A Metropolitan Police spokesman said: "Allegations that one of the (alleged) victims was involved in taking Class A drugs have been made during the course of this trial. At this stage the Metropolitan Police will not be investigating these allegations. Should any evidence, and that includes material from the trial, that could be investigated come to light this decision will be reviewed. Card spending At the trial, Ms Lawson said she took cocaine with former husband John Diamond when he found out he had terminal cancer and in July 2010 in the later years of her marriage to Mr Saatchi. She told the jury: "I have never been a drug addict. I've never been a habitual user. There are two times in my life when I have used cocaine. She said she took cocaine with Mr Diamond on six occasions. "It gave him some escape," she said. The idea that I am a drug addict or habitual user of cocaine is absolutely ridiculous. The trial heard that Francesca and Elisabetta Grillo spent £685,000 on credit cards owned by Ms Lawson and Mr Saatchi. They claimed Ms Lawson allowed their spending to cover up her cocaine use. Businessman and art dealer Mr Saatchi, 70, has yet to comment about the case.
