Green Party leadership up for grabs.

So Caroline Lucas is to stand down as leader of the Green Party. Apparently this is all about letting other top Greens have a go at leadership and who am I to doubt this. Leaders are  still something of a novelty in the Green Party so it stands to reason that lots of members, keen to spend less time with their families, will  fancy giving it a try. All very laudable and democratic but some more cynical political observers, unused to such altruism, will be sniffing around the undergrowth in search of scandal. What could be the guilty secret that has forced Caroline to step down before the organic matter hits the wind turbine?  Does the Brighton MP drive a Hummer or perhaps host wild parties where the guests sit naked under patio heaters eating tropical fruits torn from the mouths of starving children and flown half way round the world at vast expense? Just asking.
