The consumer group Which? has reported Tesco to the UK’s competition watchdog over the supermarket’s failure to provide detailed pricing information on its loyalty card offers.

The group said the UK’s largest retailer had not clearly explained the unit price of deals for its Clubcard holders – such as the price per 100g or 100ml – so that shoppers could easily compare value for money between different sized packages, bottles, brands and retailers.
