Russell Brand and Mark Steel addressed tens of thousands as they marched through central London and gathered on the Houses of Parliament.
50,000 people marched from the BBC’s New Broadcasting House in central London to Westminster this last Saturday.
“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 second march is planned for October.
Clare Solomon said: “It is essential for the welfare of millions of people that we stop austerity and halt this coalition government dead in its tracks before it does lasting damage to people’s lives and our public services.”
Sam Fairburn, said: “Cuts are killing people and destroying cherished public services which have served generations.”
“This is a call to all those millions of people in Britain who face an impoverished and uncertain year as their wages, jobs, conditions and welfare provision come under renewed attack by the government.”
“The assembly will provide a national forum for anti-austerity views which, while increasingly popular, are barely represented in parliament.”
A spokesman for the prime minister declined to comment.
