Come on David, go down to your shed and grab your bucket! There are photo opportunities you're missing in your very own underwater constituency.
What are you doing flying (yup that is helping the whole climate change thing ain't it David) off to Rwanda to get your pretty photos in the press, when you could be helping out with your bucket in Witney?
As your new propaganda advisor, I advise you should fly home, get your bucket out of your shed, phone the press and get them to meet you splashing around in the water for a bit. We'll try and spin it so it looks like you're rushing home from important party business to save the people of Witney from the evil proletarian waters, just think of all the votes you'll get David!
