The grocery retail market in the UK is highly competitive. Big supermarkets are constantly vying with each other to win and retain customer loyalty. In years gone by, the market was dominated by the ‘big four’ – Tesco, Sainsbury’s, Asda, and Morrisons. More recently though, their grip on the market has been increasingly loosened by newer entrants. Discount supermarkets such as Lidl and Aldi, have made a name for themselves with a focus on value for money. It’s against this backdrop that an interesting trade mark dispute has arisen between Lidl and Tesco.
