Skip to 0 minutes and 5 secondsI've been at this business 45 years, OK? And I suspect that the first meeting of the Green Party that I went to when I was a raw, unsophisticated campaigner at the age of 24-- I guess the first question would be, yeah, brilliant, but what are we meant to do? And it's still the same question. And I ask myself, you're not trying. You know what you bloody well should be doing. It really isn't that difficult.
