More heads will roll at the BBC, says Lord Patten

No end to the bloodletting as chairman’s own job comes under pressure, while broadcaster refuses to name executive who signed off on Newsnight report

Lord Patten, the chairman of the BBC Trust, has admitted the beleaguered organisation needs to "get a grip" and indicated that more heads will roll following the resignation of the Director-General, George Entwistle.

With the BBC caught in a crisis that threatens to eclipse even that which engulfed the organisation in the wake of the Hutton Inquiry eight years ago, an overhaul is expected at the top of the corporation.

A report on Newsnight's flawed investigation of care-home abuse in North Wales, which prompted internet speculation in which the former Conservative Party treasurer Lord McAlpine was falsely linked to a paedophile ring, has been submitted and will lead to sackings on the BBC2 show, which could be closed down.

In an interview before his resignation, Mr Entwistle said the story had been signed off by a member of the 12-strong BBC management board. The BBC was last night refusing to disclose the name of the board member.

Lord Patten said yesterday that he was looking into the report by Ken MacQuarrie, head of BBC Scotland, and that some BBC staff could lose their jobs as a result of its findings.

"We are looking into a report into how that Newsnight programme was made," he told Channel 4 News. "We've also got other reports as you know by the former head of Sky [Nick Pollard] and a distinguished judge [Dame Janet Smith] and they will involve us in making some tough decisions and those decisions may involve people's jobs."

The BBC Trust walked into more controversy after confirming that Mr Entwistle would receive a full 12-month's salary of £450,000 in lieu of notice. John Whittingdale, the chairman of the Commons Culture, Media and Sport Committee, said he could not see the justification for such a large pay-off.

Senior BBC sources are expecting the Director General's role to be split in two following Mr Entwistle's obvious difficulty in coping with the fallout from the Jimmy Savile scandal and editorial failings by Newsnight while trying to manage his other responsibilities.

Mr Entwistle's successor could have a narrower role, with responsibility for the BBC's journalism being passed to a deputy. The BBC previously operated such a system but Mark Byford's role as Deputy Director General on a salary of £475,000 was dispensed with last year as the organisation came under fire for having too many senior managers. Lord Patten said yesterday that the next leader of the "very large and complex organisation" would need "the right sort of support". He said that the BBC Trust "will make changes".

Following Mr Entwistle's departure, the head of BBC Worldwide Tim Davie has assumed the role of acting Director General. It has emerged that Mr Davie, a former executive with the food company PepsiCo who joined the BBC as marketing chief, was head of the editorial chain of command for the controversial Newsnight story, although it is understood that the matter was not referred to him.

It was signed off by a member of the management board and though they have been named in the MacQuarrie report, the BBC would not identify them yesterday.

As the BBC considers the report and awaits the findings of the Pollard and Smith inquiries, the futures of many of its senior executives, including director of news Helen Boaden and her deputy Stephen Mitchell remain uncertain. It is understood that the pair – as well as Mr Entwistle – had been taken off the editorial chain handling the Newsnight story due to their connections to the same programme's Savile investigation, which dealt with similar subject matter.

Lord Patten rejected the idea that he should have warned Mr Entwistle or taken other action after seeing a tweet from Iain Overton, head of the Bureau of Investigative Journalism – which worked with the BBC on the investigation, predicting a story about "a very senior political figure who is a paedophile" . Mr Overton was yesterday discussing his future with the Bureau's trust body. Lord Patten, who insisted he would not be resigning as the BBC Trust chairman, said: "When I saw that I didn't try to intervene in a programme and it is completely absurd to suggest that I should have done."

The chairman of the Commons Culture, Media and Sport Committee John Whittingdale said senior staff who were directly involved must also be held to account. "If George Entwistle was unaware of the programme, which he says he was, then clearly somebody below him took the decision that it was right to broadcast it," Mr Whittingdale said. "That was a terrible decision."
