Labor asks for "please explain" after alleged leak of Hayne Royal Commission final report

The corporate regulator ASIC is under increasing pressure to investigate claims that parts of the Hayne Royal Commission final report were leaked allowing insider traders to make millions. 

Labor and the Greens say there valid suspicions that Kenneth Hayne's final report into the banking sector made its way to some investors before its official release after the stock exchange closed on Monday. 

Treasurer Josh Frydenberg has rejected the allegations saying that all briefings and lockups for the media, stakeholders and regulators were done under strict security to prevent damaging leaks. 

But CMC Markets strategist Michael McCarthy tells ABC's Peter Ryan there is no evidence of  leak to investors.
