PwC tax leak crisis could see more executive heads roll, Emeritus Professor Ian Ramsay warns

The global consulting firm PwC is battling to salvage its reputation for trust amid allegations that it misused a confidential briefing to help clients get around multinational anti-tax avoidance laws.

The scandal has claimed the scalp of PwC's Australian boss Tom Seymour and corporate veteran Ziggy Switkowski has been hired to conduct an internal review warning that if necessary more heads could roll.

Corporate law expert Emeritus professor Ian Ramsay from the University of Melbourne is one of the many observers gobsmacked by the implications.
