Hundreds of people in polar-themed costumes are expected to join an Arctic-inspired street parade which will stream through central London as part of a global day of action to protect the pristine region at the top of the world.
The crowd of white-clad Arctic defenders, including people wearing polar bear costumes will be led by the world's largest polar bear puppet - a three-tonne marionette the size of a double decker bus, named Aurora. The giant bear will be operated by a team of 15 puppeteers.
The family-friendly parade will walk past Westminster heading for oil giant Shell's HQ on the Southbank, where a creative and peaceful demonstration against the company's Arctic drilling plans will take place.
