Jan Cameron’s former business adviser was named by the corporate regulator as a star witness in its prosecution of the Tasmanian businesswoman at the same time as he was pursuing a claim in a Caribbean Court to freeze her $185 million windfall from the sale of shares in Bellamy’s Organic.

In the Hobart Magistrates Court on Wednesday, Ms Cameron reiterated her not guilty plea to criminal charges laid by the Australian Securities and Investments Commission alleging she failed to disclose her links to the Black Prince Private Foundation, a major investor in the infant formula company.
