In June 2013, while dining at Scott's, a London seafood restaurant, Saatchi was photographed with his hands grabbing Lawson's throat. The day after the pictures were published, Saatchi said they were misleading and depicted only a "playful tiff". He was formally cautioned for assault and voluntarily accepted the caution following an investigation by the police.
In early July of the same year it was announced that the couple were to divorce. Lawson cited ongoing unreasonable behaviour in her divorce petition. On 31 July 2013, seven weeks after the incident, Saatchi and Lawson were granted a decree nisi. They reached a private financial settlement. R v Grillo and Grillo, a trial for fraud involving the former couple's two Italian-born personal assistants, sisters Elisabetta and Francesca Grillo, began on 27 November 2013.
