Tesco is Britain’s favorite supermarket. With 2,000 stores and 15 million customers a week, it’s almost twice as big as its nearest rival. Dispatches shows how Tesco could soon become even bigger, and asks if this retail giant is abusing its power. Dispatches’ information shows how that dominance could become even greater. The programme examines the ways in which Tesco avoids paying tens of millions of pounds in tax by exploiting legal loopholes and using complex networks of companies and partnerships here and overseas.
