Sir John Bourn, the former independent adviser on the Ministerial Code, said there was no need for David Cameron to wait for the Leveson Inquiry to examine the Culture Secretary before beginning his own investigation.
Mr Cameron said yesterday he was prepared to order a Whitehall investigation into Mr Hunt’s overseeing of the Murdoch bid for BSkyB, but only after Mr Hunt gives evidence to Lord Justice Leveson next month.
The Prime Minister also set the stage for questions about his own actions when he admitted discussing the bid for BSkyB with James Murdoch while his Government was deciding whether to let the takeover go ahead.
Lord Butler of Brockwell, a former cabinet secretary, told BBC Radio Five Live there was “no doubt that the letter of the Ministerial Code has been breached” in Mr Hunt’s case.
However, he described the breach as “a technical sin” that was “not enough for a man’s career to be ruined”.
