Rupert Murdoch’s appearance in front of the House of Commons Culture, Media and Sport Select Committee exposed a host of corporate governance issues.

While the headlines will focus on the young man who attempted to attack Rupert Murdoch with a mock custard pie, and the way his wife fought back against the assailant, the media magnate’s inability to answer a series of key questions was the most significant feature of the hearing.

Murdoch senior has ultimate responsibility for corporate governance at News Corporation and its News International subsidiary, and Murdoch admitted that the oversight of operations had failed.

Murdoch flatly refused to accept personal responsibility for the phone hacking scandal that has engulfed his media empire, instead blaming those he delegated to run his business units and those who they appointed to investigate wrong doing when it emerged.

In their answers to the committee, Rupert Murdoch and his son James repeatedly said they did not know of crimes or misdemeanours, until very late in the day.

While few organisations have ever had allegations of institutionalised criminality levelled against them, the experience of watching the Murdoch’s admit to the failings of their organisations will put a renewed focus on corporate governance in organisations round the world.
