*Should note, actually, that Kantar does not have a squeeze question, but does not offer 'don't know' as an option, which has a similar effect.

Many thanks to Patrick Flynn of FocalData for compiling this analysis which explains why we have such variance in the polls and fits in with this morning’s thread.

To quote Patrick, ‘These is your cheat sheet for identifying which pollster belongs in which group. Yellows and greens tend to show reduced Labour leads.’

It is worth reviewing polls when they come out to this cheat sheet.
