Stanley Johnson told Extinction Rebellion demonstrators that they had "exactly the right things in mind" with their demand to slash carbon emissions to zero. He also said the eco-movement was "tremendously important. ... It is absolutely clear to me that we have been moving far too slowly on the climate change issue."
More than 500 people have been arrested in London since protesters began blocking roads and bridges on Monday, part of a global wave of protests that have also hit New York, Paris, Berlin and Madrid.
Boris Johnson called the protesters "uncooperative crusties" who should abandon their "hemp-smelling bivouacs."
Stanley Johnson said: "I wear that badge with pride."
