Bradley Birkenfeld has been called the man who destroyed Swiss banking secrecy and one of the most important financial whistleblowers in history.
His revelations about how his former employer UBS helped thousands of wealthy clients evade tax led to the bank paying a $780 million fine and forced Switzerland to change its banking laws.
But despite having handed US authorities details about thousands of tax evaders, Mr Birkenfeld ended up being the only person involved to serve time in jail.
The former banker tells Times Talk that whistleblowers must be financially compensated if they are to be encouraged to speak out, and says he would be happy to meet with Maltese MPs to discuss ways to improve local whistleblower legislation.
