'That Piers Corbyn made me feel squeamish and embarrassed just listening to him.'
Really? Because you believe that man made climate change is a myth and deserved a better champion? Or, more likely, is your embarrassment just a posture, triumphalism masquerading as embarrassment?
(as an aside, Piers Corbyn, like his brother, my Member of Parliament, Jeremy Corbyn was active on the left since the 1980s, when he was a contributor to London Labour Briefing - not suggesting, of course, that that does anything for his argument on climate change)
