The debate over retailer expansion in the UK swung back into the spotlight this week with the country's regulator standing firm on a planning test - much to the chagrin of Tesco. Rumours on Wal-Mart's intentions over Russia resurfaced as the world's largest retailer was linked with local grocer Kopeyka. In France, Carrefour claimed to be "encouraged" despite its quarterly sales falling year-on-year; while ailing milk group Entremont Alliance attracted a joint bid from peers Sodiaal and Bongrain.
