Charles Saatchi has renewed his attacks on ex-wife Nigella Lawson, this time questioning her parenting skills and saying she cheated on her dying husband with him.
Saatchi attacked Lawson's parenting skills after she admitted taking drugs in front of her child in a recent court case, the Telegraph reported.
Saatchi, 70, said in a statement: "The truth is that she was taking illegal drugs secretly throughout the last few years of our marriage, often with her own child when she was far too young to even smoke or drink."
Saatchi seemed to be upset that Lawson continued to win the public relations battle since he revealed her drug use in court and added: "That this practice seems to be considered acceptable behaviour in sections of the press is deeply disturbing, as is the notion that you can teach your children that drugs are a justifiable way to make 'an unbearable situation bearable'."
The outburst follows his testimony at Isleworth Crown Court in November, during the trial of the Grillo sisters accused – and subsequently cleared – of defrauding him.
During the trial, Saatchi testified: "I have never, never seen any evidence of Nigella taking any drugs whatsoever."
Saatchi's latest comments came after hearing Lawson's own evidence in court.
In her testimony, she admitted smoking cannabis in front of her children.
She also said she took cocaine on six occasions, to help her cope with her first husband John Diamond's terminal cancer and later as her marriage to Saatchi began to break down.
The television cook has denied claims she regularly took drugs.
Saatchi also said in the statement that their relationship started six months before Diamond's death, the Daily Mirror reported.
"Nigella and I began our relationship during the last six months of her husband John Diamond's life, rather than after his death as she [Nigella] stated in court," he said in a statement.
"Looking back at that time, I very deeply regret that this betrayal of John occurred."
A representative for Lawson denied all the allegations and said it was a smear campaign against her.
The couple's marriage disintegrated last July after publication of photographs showing Saatchi with his hands around Lawson's throat during an argument at a restaurant in London.
Saatchi gave the restaurant staff more than £1000 (NZ$2000) to share among themselves as a Christmas present, the Sunday Telegraph reported.
"Charles was very grateful for all the help that they had given him throughout the year," one of his friends said on Saturday.
