She joined Russell Brand, Owen Jones, Mark Steel and others in calling on the government to end its policies of austerity.

Caroline told the crowds: “We have a message for the government. It wasn't the poor who caused the economic crisis. It wasn't people on Jobseeker's Allowance who brought down the banks. It wasn't people with disabilities who wasted billions speculating on risky financial markets. So that's why we're here to say: stop punishing the poor."
