Far be it from me to give advice to the Green Party. From their insistence that ordinary people put up with being poorer and colder to ‘save the planet’ to the alarmingly high number of Israelophobic, 7 October-denying cranks on their candidates list, I’m really not a fan. Still, I’d gently suggest that the golden rule for any Green vying for election is to practise what you preach on climate.
