In war, truth is the first casualty. In the Scottish independence referendum, the same can be said for trust in the BBC.
Last week SNP leader and first minister Alex Salmond accused BBC political editor Nick Robinson of "heckling" him at a press conference, and today he said London-based journalists were guilty of "unconscious bias".
“If the BBC were covering, in my estimation, any referendum, in any democracy, anywhere in the world, they would cover it impeccably, in a balanced fashion," he told the Sunday Herald.
"What they don’t understand is they’re players in this.”
On that theme, hundreds of Yes supporters - chanting "BBC, shame on you" - gathered outside BBC Scotland's headquarters in Pacific Quay, Glasgow, some brandishing placards labelling the BBC as an anti-democratic and demanding the sacking of Robinson.
