A BBC report which wrongly implicated the former Tory treasurer Lord McAlpine in child abuse should never have been broadcast, the corporation’s director general said today.
George Entwistle described the Newsnight report on the North Wales children’s home scandal as “unacceptable”.
He warned that staff involved in the programme shown last week could now face disciplinary action.
The BBC last night issued an unreserved apology after one of the victims the programme spoke to admitted he had wrongly identified Lord McAlpine as the man who abused him in the 1970s and 1980s.
Mr Entwistle told the BBC Radio 4 Today programme: “We should not have put out a film that was so fundamentally wrong. What happened here is completely unacceptable.
“I have taken clear and decisive action to start to find out what happened and put things right.”
He said that he expected a report into what went wrong, being carried out by the director of BBC Scotland Ken MacQuarrie, to be on his desk by Sunday.
“Further action will follow from that – disciplinary if necessary.”
Mr Entwistle admitted the corporation was facing a ``bad crisis'' of trust in the wake of the Jimmy Savile scandal - including a decision to drop a Newsnight investigation exposing the late DJ as a serial child abuser.
Although the programme did not name Lord McAlpine, the peer has indicated that he now intends to sue the BBC after it led to him being identified on the internet.
Mr Entwistle insisted however that he had no intention of resigning, although he accepted that his future now lay in the hands of the BBC Trust.
“I am doing the right things to try and put this stuff straight. I am accountable to the Trust in that endeavour. If they do not feel I am doing the right things, then obviously I will be bound by their judgment,” he said.
British Prime Minister David Cameron declined to comment on Newsnight today, as he met the Military Wives Choir and a group of Royal Marines at Downing Street to launch this weekend's remembrance events.
