Protests will be held across the country today against a 'secret' trade deal between the EU and the US that could threaten jobs and public services.
Hundreds of people are expected to march in London, Edinburgh, Brighton, Manchester, Cardiff, Nottingham and other areas.
Those opposed to it say the proposed deal, known as the Transatlantic Trade and Investment Partnership (TTIP), threatens increased privatisation of schools and the NHS, would cut food and environmental rules, and cost jobs.
Nick Dearden, director of the World Development Movement, said: "The deal would hand multinational companies unprecedented powers over life in this country."
