What's your background?
I was special adviser to Margaret Beckett for three years when she was Secretary of State for the Environment.
What's your analysis of Labour's green agenda?
There are elements of Labour's environment record that the party can be proud of - the increase in recycling rates, for example. But overall it hasn't inspired either the environmental movement or the public.
That said, Charles Clarke recently named the environment as one of the areas in which Labour needs to do more. This and the messages from new environment secretary David Miliband suggest Labour heavyweights are debating whether they need a step-change in environmental action.
How about the Tories?
There is a huge media circus around the Conservatives, but the substance isn't there yet. Cameron has set up policy commissions, but it's not clear when that process will conclude or, more importantly, what Cameron will do in the aftermath.
And the Lib Dems?
Data suggests the Tories are getting tremendous coverage for what they're doing on the environment, but they haven't shifted the public's view that, of the three main parties, the Lib Dems have a lead on the environment.
If the Lib Dems don't get more coverage, that is going to erode.
