From Survation with a poll of 1682 in the UK and a sub-set of 157 Scots for 26-27 October:

UK:

• Con 26.8%
• Lab 51.2%

Scotland:

• Con: 12%
• Lab 27.8%
• SNP 54.4%

Signs perhaps of a partial, post Sunak, Con recovery at 30% in England but little sign of either a Labour surge or a Con recovery in Scotland.

This follows People Polling on 26 October with 99 Scots, which had Labour at 37% (51% in UK) but Cons at only 7% with SNP at 47%:

Techne, also on the 26-27 October, do not have a Scottish sub-poll.

Small sub-polls, I know, but both saying the same thing – Sarwar’s Starmerite Labour does not appeal.
