Friends of TV chef Nigella Lawson have said her ex-husband Charles Saatchi is “still at it” after he was blamed for her being banned from boarding a plane to the US following her admission of drug use in court.

“He’s still at it,” said an “impeccable source” quoted in the Mirror, who spoke out after last weekend’s incident.

“She feels she will never get away from him.”

Lawson’s marriage to art collector Saatchi ended shortly after he was pictured grabbing her throat.
