A friend (who doesn't live in Islington North) was canvassing for Corbyn recently; he said the volunteer team included some people from the Midlands. Generally got positive responses when knocking on doors; one bloke waved a knife at him, but he was having his dinner...
I read elsewhere one of Corbyn's team saying their biggest obstacle was voters not realising Corbyn was no longer standing as a Labour candidate - as posted above, voters might just assume he's still the Labour guy and tick Labour. It seems astonishing to me, but I guess it's an example of how disengaged a lot of the UK population are from politics - not that interested and wouldn't have read about Starmer's purge* - yet they are sufficiently motivated to vote
*Starmer's Purge would've been a good name for a English Civil War-era speed metal band
