YouGov and the Times have some fresh Syria polling tonight, conducted on Monday evening and during the day on Tuesday. It shows a sharp drop in support for airstrikes since YouGov’s polling a week ago, but the overall balance of opinion is still in favour: 48% now support RAF airstrikes against ISIS in Syria, 31% are opposed. A week ago the figures were 59% to 20%.

Some of this may be the fading impact of the Paris attacks, some people recoiling from the reality of intervention. I suspect a lot is also partisan polarisation: there is little movement amongst Conservative voters, but there is a huge turnaround amongst Labour voters. Whereas a week ago 2015 Labour voters broke in favour of airstrikes by 52% to 26%, they have now turned against. Among 2015 Labour voters 42% are now opposed (up 16 points), only 35% now support (down 17). While Jeremy Corbyn’s stance is still at odds with wider public opinion, now both Labour voters and Labour members agree with him: it is his opponents within the PLP who are at odds with the rest of the Labour family.

But if public opinion is moving against intervention, there’s not a sign of it helping Jeremy Corbyn with the wider public, or hurting Conservative support. Corbyn’s own ratings are down – 24% of people now think he is doing well as leader, down from 30% last week; 65% think he is doing badly. Voting intention figures are CON 41%, LAB 30%, LDEM 6%, UKIP 16%.
