An estimated 40,000 people marched in London as part of a worldwide climate mobilisation ahead of the UN summit in New York.
The march, on an unseasonably warm afternoon, was characterised by creativity and diversity, with a large number of contributing organisations and groups, and a lot of home-made banners and props. A protest notably unmarred by the usual sea of Socialist Worker placards.
The main rally ended with a minute’s silence which was intensely observed by the mammoth crowd, an eerie quiet enveloping the streets around Westminster.
The official march was followed by a spontaneous visit by a crowd of around a thousand to the Tory HQ nearby.
Earlier in the day, activists targeted the British Museum with a creative and poignant protest action over BP arts sponsorship.
