At a lead of 17-points, this is the joint second highest EVER recorded in the dating back to 1992, only beaten by a Gordon Brown crisis of June 2008. The Tories 43% is two-points adrift of its highest share ever recorded by ICM (three times after the 1992 election, Jun-08 and Nov-08 plus 44% on three occasions straddling 08-09). We did have them on 43% back in July this year.
As for Labour, their 26% has only been ‘beaten’ by 25% in Jun 08 and Aug 09, and the last Guardian/ICM at this level was Sep 09 (the only other time). However, ICM did also put them on 26% three weeks’ ago for a Sunday newspaper.
In fact though, Labour’s share has only been saved from a record low by ICM’s standard post-fieldwork adjustment techniques, which ordinarily help the Tories. The reason for this is that this week, there are a high number of people who say they voted Labour in 2015 but DK/refuse to say what they will do next time, and our reallocation of them back to the party for they voted for ends up adding two-points back to Labour.
Labour’s struggles are especially prevalent among women (Tory split 39% vs 52% in favour of women).
We also see further decline in the UKIP share, possibly prompted by recent fisticuffs and the return of Nigel Farage. At 11% they dip below their 2015 election share for the first time with ICM and it’s the lowest we’ve ever had them on an online poll (although phone polls pre-2015 had them lower very often).
