It appears polling companies, in the hope of correcting the mistakes they made in 2015, have changed weighting (in some cases substantially). Due to, presumably, Labour supporters not actually voting, this bumps Tory predictions.
Generally this is polling stuff, and nothing particularly weird. But, if CORBO! is different, and does get the youth vote out, it could mean polls are too conservative. (If he's not, and this election is like others, polling may be more accurate).
