The detailed data from the latest YouGov Times poll shows that when asked just 50% those sampled who voted Labour at the last election chose Corbyn in response to who would make the Best PM.
This is the worst polling for the LAB leader since the election and has Corbyn showing the same sorts of ratings from past party voters as Ed Miliband was getting ahead of GE2015.
This is all a long way from the post-GE2017 polling when Corbyn’s support on this question amongst who had voted for the party was touching 80%.
It comes at a time when his leadership has been under sharp scrutiny over the bespoke antisemitism policy that has caused so much anger in the Jewish communities and amongst Corbyn’s own MPs.
The strongest thing in Corbyn’s favour at the moment is that his supporters control just about all the lvers of power within the party and of course he continues to have the strong backing of members.
He isn’t going anywhere and it is hard to see him and close adviser, Seumus Milne climbing down on the definition of antisemitism.
