The Tescopoly Alliance was launched in June 2005 to highlight and challenge the negative impacts of Tesco’s behaviour along its supply chains both in the UK and internationally, on small businesses,
on workers, on communities and the environment. The Alliance represented a diverse group of organisations. Members included Banana Link, Friends of the Earth, GMB London, Labour Behind the Label, nef and War on Want.
The campaign advocated national and international legislation needed to curb the market power of all the major British supermarkets. The Alliance was part of a multi-stakeholder effort calling on the UK Government to establish an independent Ombudsman to monitor and enforce big supermarkets. In August 2010 the Government announced the creation of a Groceries Code Adjudicator (GCA) in a bid to end the unfair treatment of farmers, suppliers and shoppers. In June 2013 Christine Tacon started in the new role of Groceries Code Adjudicator (GCA).
Tescopoly was not an organisation in its own right. It was facilitated and supported by the Alliance members, with additional financial support from independent charitable trusts. The website provided a resource for local campaigners but all local groups are independent and are not affiliated to the Tescopoly Alliance.
