There's a stockbroking house whose CEO has made a fortune from alleged insider trading and other forms of market manipulation at the expense of clients. He has allegedly salted tens of millions of dollars of the illegal proceeds into Swiss accounts to avoid detection.

In his previous roles in wealth management organisations he left a trail of destruction.

If our legal system was different, the scandal would have been exposed and the CEO would have been called to account.

I can't tell you who he is or identify the companies involved because a whistleblower who told me about the story pulled out of going public in late 2016.

Personal threats, pressure from their family not to go public and a failure of our laws to protect whistleblowers culminated in a settlement in return for a gag order. The corporate regulator was handed a file more than two years ago.
