The BBC is institutionally biased because they stand to lose 10% of their licence fee. I have heard they received some EU funding, but from their POV they probably made some money from exporting programming within the common market. I voted Remain myself although I do have some misgivings about the EU. (I recently debated an American online who thought the BBC's current panic about licence fees was to do with USAID. Not even close. Although British TV has been swamped with US imports.)

"The 45" has a resonance in Scottish history and it is a bit of a coincidence the Yes vote was stuck at that rather than 47 or 44.

Having neutral international observers was a no brainer, but the SNP often seems to trust the system they're trying to break up much more than it should.
