Tens of thousands of people marched through central London on Saturday afternoon in protest at austerity measures introduced by the coalition government. The demonstrators gathered before the Houses of Parliament, where they were addressed by speakers, including comedians Russell Brand and Mark Steel.
An estimated 50,000 people marched from the BBC's New Broadcasting House in central London to Westminster.
"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," said Brand.
"This will be a peaceful, effortless, joyful revolution and I'm very grateful to be involved in the People's Assembly."
"Power isn't there, it is here, within us," he added. "The revolution that's required isn't a revolution of radical ideas, but the implementation of ideas we already have."
A spokesman for the People's Assembly, which organised the march, said the turnout was "testament to the level of anger there is at the moment".
