We heard from various commentators around 9 or 10 days ago that the Derek Mackay case combined with the Salmond case coming to court would damage the SNP. Reporting Scotland’s Brian Taylor referred to the Mackay case as a ‘calamity’ for the party.

A sub-poll published today based on fieldwork only 5 days later suggests that, as before, the errors of single politicians do not materially change the opinions of a mass movement.

The Opinium survey on 12th February does not have a Scottish breakdown but has support as a share of the overall UK-wide survey at 6% up from 5% in their last poll on 10th December 2019.
