Former MP Richard Worth is earning a living solving other people's arguments.

Worth, who quit Parliament in June for "personal reasons", advertised his services as a barrister specialising in dispute resolution, mediation and arbitration in Law News this month.

Before entering Parliament, he was chairman of top law firm Simpson Grierson, boasting an MBA, a PhD and a master of jurisprudence.

His latest ad doesn't even give an office address - just a mobile number and an internet email account.

Worth declined to comment.

The former Minister of Internal Affairs endured a controversial 10-year Parliamentary career.

He resigned after losing the Prime Minister's confidence and the start of a police inqury into allegations of a sexual nature made by a Korean businesswoman.
