Bill Shorten says suspect a "coverup" if no convicted banker goes prison

Opposition Leader Bill Shorten says Australians should suspect a coverup if no banking executive convicted of criminal conduct goes to prison. 

The National Australia Bank is in damage control after yesterday's resignations of chief executive Andrew Thorburn and chairman Ken Henry. 

Former labor senator and NAB shareholder Chris Schacht tells ABC's Peter Ryan that in addition the the departures of Mr Thorburn and Dr Henry, the rest of the NAB should consider leaving.
