The BBC has been dragged into a fresh storm over a second Newsnight paedophile investigation, it emerged today.
Editor of the London-based Bureau of Investigative Journalism, Iain Overton, mysteriously tweeted that a 'senior political figure' was to be outed as a child-abuser on the programme this evening.
The investigation about the unnamed man, who is alive, is being looked at by the BBC's legal team, MailOnline understands, but the corporation is refusing to confirm the probe exists.
This is despite Mr Overton's crystal clear message online: 'If all goes well we've got a Newsnight out tonight about a very senior political figure who is a paedophile.'
Mr Overton's bureau is a not-for-profit organisation which works with news outlets to publish in-depth investigations. It says it has been working on this project for the BBC.
It piles more pressure on the beleaguered corporation after last month it was revealed Newsnight dumped an investigation into paedophile Sir Jimmy Savile, even though they had interviewed his victims.
Channel Four political correspondent Michael Crick says he has spoken to the man at the centre of the allegations, who denied that he was a paedophile and said he would sue if Newsnight broadcasts anything on him tonight.
He also added that the man said he had not been approached for a comment by the BBC, despite it being earmarked for tonight's Newsnight.
The Metropolitan Police have told MailOnline they have not been handed anything on the subject of the investigation.
