Hundreds of protesters had also blocked Waterloo Bridge, which was closed in both directions, with campaign group Extinction Rebellion declaring on their Twitter page: "We have taken Waterloo Bridge!"
A huge climate change demonstration has got underway in London with protesters blocking roads and causing "criminal damage" in a deliberate attempt to get arrested. Some activists also glued themselves to windows.
