BBC CHIEFS were under new pressure last night to hand over interviews with Donald Dewar and Holyrood project architect Enric Miralles after Tory leader David McLetchie accused them of “double standards”.

Kirsty Wark’s production company interviewed the two central figures in the Holyrood debacle about their roles in its construction for a BBC documentary The Gathering Place.

However, the BBC have refused to hand over tapes of the meetings to Lord Fraser’s Inquiry which is currently probing the rocketing costs at the Holyrood site. They say they had a confidentiality agreement with the men, which stressed that no material would be revealed until the programme was broadcast.

Last night Mr McLetchie demanded a rethink, pointing to the BBC’s Panorama programme which contained previously unseen footage of an interview with Dr David Kelly.

The BBC has confirmed that a transcript of that interview was submitted to the Hutton Inquiry into Dr Kelly’s death before the programme was shown. Mr McLetchie has now written to Lord Fraser suggesting he should demand a similar treatment for his investigation.

“Given the apparent double standards being applied by the BBC, I wonder if another approach to them is now appropriate,” said Mr McLetchie.

“There seems to be one policy for the Hutton Inquiry and another for the Holyrood Inquiry and the fundamental question is ‘Why?’

“Why has no transcript of the interviews given for the ‘Gathering Place’ programme been made available to the Holyrood Inquiry?

“You can’t have one policy for one inquiry and one policy for another and I hope very much that Lord Fraser will act on this and that the BBC governors will reverse their inappropriate decision that is frustrating the inquiry, undermining confidence in the inquiry and undermined confidence in the BBC itself.”
