Tesco is to invest £150m ($226m) to relaunch its Clubcard loyalty scheme as it fights to regain market share from discounter chains such as Lidl and Aldi and its major supermarket competitors.

The UK’s leading retailer has launched a scheme that allows customers to trade in Clubcard vouchers for offers in store that will enable them to double their value on certain goods in categories, such as health and beauty and clothes.
