Comedian Russell Brand has called on thousands of protesters to be part of a "peaceful, effortless, joyful revolution" that seizes power back from Westminster.

The comedian, who this year implored voters to abandon the current political system, told crowds gathered in London's Parliament Square that MPs no longer represented the people. Brand said: "The people of this building [the House of Commons] generally speaking do not represent us, they represent their friends in big business. It's time for us to take back our power." Other speakers included commentator and comedian Mark Steel and MP Caroline Lucas.
