Witnesses saw the incident in a restaurant and alerted the police. One onlooker told the Sunday People it was very disturbing. “I have no doubt she was scared, “It was horrific, really. She was very tearful and was constantly dabbing her eyes. Nigella was very, very upset.”

Saatchi, a multimillionaire art collector claiming that he was “attempting to emphasise my point”. He told the London Evening Standard that the pictures showed a “playful tiff” and gave a “more drastic and violent impression” of the incident than had been the case. He added “Nigella’s tears were because we both hate arguing, not because she had been hurt.”

However, the Metropolitan police said last night that a 70-year-old man voluntarily attended a central London police station in the afternoon and accepted a caution for assault after an investigation by the community support unit at Westminster reports The Guardian.

Heather Harvey, from Eaves, a charity that supports victims of domestic violence, said some of the language being used was shocking. “This is not a ‘row’, it is not a ‘tiff’, it is an incidence of domestic violence. There is an unfortunate myth that domestic violence only happens to a certain type of person, that it happens in dysfunctional families where people have been drinking. But it happens in every social class, and in every profession.”
