I'd take commentators claiming the Green Party of England & Wales has been beset by Left entryism more seriously if they hadn't dismissed the party in the past as a marginal force in British politics. The worry that the GPEW has widened its focus & encompassed views popular on the Left is not so much a worry about the policies the party espouses, as a concern they might actually gain more votes thereby disrupting the political class' domination of the political agenda! #politics
