Operation cleanpeace is go!

Civic responsibility is all-important, and cleanliness, as they say, is next to Godliness. So last week, to mark the one-month anniversary of our rooftop night on the houses of Parliament, a boat sped down the Thames to Westminster to do our bit for the well-being of the country with a spot of cleaning. Yes, cleaning.

So the boat crew cleaned the riverside wall quite, er, precisely, and if you use your imagination it almost looks like some sort of message might have been cleaned into the riverside grime.

Oh, well, it's a fair cop. ‘Change the politics, save the climate' is what we were going for. We thought the parallels were clear - clean up the riverside, clean up politics, clean up the climate...

But then it threatened to all go a bit Hawaii-five-oh and the river police turned up, so we beat a tactical retreat having only done the first half of the slogan. Still, in the run-up to Copenhagen it's more urgent than ever that politicians of all stripes press for bold action at the climate summit, so ‘change the poilitics' will do for the moment, and ‘save the climate' might have to come in due course.

If you're interested in what changing the politics actually looks like, read our manifesto for more details.
