A Lidl GB spokesman said: “Over the last three years, Tesco has been using its Clubcard logo to deceive many customers into believing that Tesco was price matching against Lidl or was able to offer the same great value as us.
“This infringement allowed Tesco to take unfair advantage of our longstanding reputation for great value, misleading their customers at a time when they should have been supporting them. We are pleased that the Court has agreed with us and that it will now order Tesco to stop using the Clubcard logo.”
The ruling comes amid an escalating price war among UK supermarkets, as traditional stores scramble to stop their shoppers switching to Aldi and Lidl.
The German discounters recorded sales growth of more than 25pc over the past year, compared to around 6pc growth at the traditional stores.
Last summer, Aldi overtook Morrisons to become Britain’s fourth largest supermarket, in a sign of their growing popularity among shoppers.
Tesco was approached for comment.
