Noting the dread prof’s appearance on Question Time, ‘Rosie Andrew’ sent me this from a Wings over Scotland source:

This letter-writing group organised by Scotland in Union is essentially a covert propaganda unit, clearly aware of the need to keep their existence secret.

They are writing to journalists, hoping to influence them and readers, pretending to be simply members of the public, honest citizens, if you like.

I don’t know about the legality of such practice but it’s clearly anti-democratic.

Prof Pennington was the founder of Academics Together in the run-up to the the 2014 referendum, is a founding member of the currently active Scotland Matters and judging by the mailing list above, a member of Scotland in Union.
