This latest episode in the air pollution debate signifies how politically toxic accusations against the Mayor's air pollution policies have become.

I believe that if politics is about anything, it should be about improving people's lives and bequeathing something better to our children than we ourselves inherited. If internationalism is about anything, it is about doing that for people around the world regardless of where they live. That's what environmentalism and sustainability mean to me.
