THE SNP’s depute leader has lambasted the BBC for allowing far-right and pro-Brexit parties to “dominate” Question Time audiences.

Keith Brown’s remarks come after former Conservative MSP Mary Scanlon, sitting in the audience, was allowed speak for almost a minute on Thursday’s show.

Moray Conservative and Unionist councillors Frank Brown and Claire Feaver and treasurer Jane Lax were also seen in the audience during the programme, which was held in Elgin.

Condemning BBC producers for the latest in a series of Question Time controversies, Brown said the broadcaster had “no excuse”.

"This latest episode was stuffed full of Tory plants,” he said, “but the BBC has done nothing to stop far-right and pro-Brexit parties dominating other Question Time audiences.

"We’ve been telling BBC bosses for months that they have a credibility issue with the audience selection process.

"There's no excuse for this nonsense, and the BBC has failed to stop it."

The BBC had come under fire before the show even aired for the show’s pro-Unionist panel.

The Scottish Greens believed they should have been invited on the episode in Elgin, having had no politicians on the programme since January 2018.

“It’s ridiculous the Greens are being excluded while the Unionist parties all get a chair,” a party insider said.

Brown has previously met with BBC chiefs to “outline concerns” about its management of Question Time.

The show’s producers were criticised by viewers for the repeated appearances of former Ukip candidate, Billy Mitchell, on the flagship political panel show.

The SNP were subsequently angered after Scottish Culture Secretary Fiona Hyslop’s response to Mitchell’s angry Unionist rant was heavily edited.

Responding to fierce online criticism, a BBC spokesperson said the broadcaster’s selection process ensures a “range of views are heard”.

A statement read: “Question Time does not bar people from its audience because they have held elected office or are political activists.

“There is a selection process to ensure a range of views are heard and last night’s QT audience included supporters of different political parties, including the SNP.”
