As part of Greenpeace's 'Save the Arctic' campaign, 15 puppeteers and 20 volunteers will be walking a three-ton marionette polar bear through the city. Spectators can follow Aurora the bear en route – she won't be hard to find, she's the height of a double decker bus – as sound effects of her roaring and ice cracking emanate. Aurora will start her walk at Victoria Tower Gardens next to Parilament at 12pm.
