Volunteers will head to Morpeth town centre tomorrow to protest against a proposed free trade agreement between the European Union and the United States.
They will be in the Market Place from 11am and will ask passers-by to sign the petition against the Transatlantic Trade and Investment Partnership (TTIP), which will be delivered to politicians in October.
Those who support the agreement say that it would reduce certain trade barriers and improve intellectual property protections, resulting in multilateral economic growth.
Critics of it believe TTIP would increase corporate power and make it more difficult for governments to regulate markets for public benefit.
UK campaigners, such as independent group 38 Degrees, have a number of fears, including that the deal could force NHS trusts across the country to open up to American private healthcare providers.
