Kevin Brown, eldest son of the Premier, has hired a celebrity lawyer to help him escape charges of sexually assaulting his patients.

Blair Berk is best known for helping Britney Spears, Mel Gibson, Queen Latifah, Kayne West and Keither Sutherland beat drink-driving charges.

But she has now joined Dr. Brown Jr's defence team as he bids to clear himself of allegations that could result in 27 years in jail. Kevin Antario Brown stands accused of multiple sex attacks on patients, including sexual assault of a 15-year-old girl and rape.

He is being held on $4m bail - an amount set so high partly because of fear he will try to flee to Bermuda and partly because he is also being separately investigated on allegations that he is part of a multi-million dollar medical fraud ring. The fraud allegations - that are so far unproven and not been brought before a court of law - mean that Dr. Brown will also have to disclose the full source of funds if he posts bail.

Ms. Berk is regarded as one of the best and one of the most expensive lawyers in Los Angeles, the city where Dr. Brown Jr. operated his medical practice. Dr. Brown Jr. is due in court on October 20 for a pre-trial hearing.
