Britain’s biggest supermarket chain Tesco recorded the fastest growing sales of the country’s four largest players in the Christmas quarter, as inflation returned to the grocery market after more than two years of falling prices. Market researcher Kantar Worldpanel said Tesco sales grew 1.3 percent during the 12 weeks to Jan. 1, outperforming no.2 chain Sainsbury’s , whose sales fell 0.1 percent, Asda , down 2.4 percent, and Morrisons , up 1.2 percent.
