Paul Mason wrote this on Twitter yesterday:
Until Johnson unleashed his cabinet of libertarians and semi-fascists you could hedge bets on Corbyn's current strategy: now that's over - there has to be an alliance of the centre and the left to stop Brexit follow[ed] by 5 years of triumphal racism
I doubt [simple] opposition could create such an alliance. It has to be a positive alliance, for the Green New Deal, constitutional reform, respect for devolved government, pro strong relations with Europe, and for equality. Then it may have a chance, and a manifesto
What are the chances? A phrase involving hen's teeth comes to mind, I fear.
But I am glad some who have given Corbyn the benefit of the doubt are now rethinking.
