There was no mention in Zack Polanski’s self-serving apologia of the real reason why we need the Green party – to insist unremittingly on putting the climate and ecological crisis top of the political agenda (Yes, it’s been a tough week for the Greens: but don’t lose sight of how we’re transforming British politics, 11 October).
Polanski should recognise that it is his own downplaying of that task in favour of populist foreign-policy posturing (along with bashing the rich) that has fuelled the anti-Jewish entryism he deplores, but isn’t quite brave enough to call out.
