Harvey Weinstein’s lawyer is facing prosecution for his involvement in the use of gagging orders to silence victims of sexual harassment.

Mark Mansell, who drew up the agreement signed by the Hollywood mogul’s personal assistance Zelda Perkins, has been referred to the solicitor’s disciplinary tribunal where he could be fined or struck off.

The news will be a blow for the reputation of the magic circle law firm, Allen and Overy, where partners like Mr Mansell last year took home a profit share in excess of £1.6million.

The Solicitor’s Regulation Authority (SRA) referred the case to the tribunal two years after they were first alerted to the agreement signed by Ms Perkins, which prevented her talking to her therapist or potentially the police about the sexual harassment she had suffered.

It comes amid renewed scrutiny on the use of non-disclosure agreements (NDAs) in the wake of the Telegraph’s investigation into Sir Philip Green which revealed that the Topshop owner paid huge sums, in one case in excess of £1million, to silence allegations of sexual and racial harassment.

The SRA is understood to also be looking into the grievance procedure and subsequent NDAs signed by at least one of Sir Philip’s previous employees who accused the billionaire of sexual harassment.
