Sir, It’s clear looking at the value retail sector that we have reached a moment where retailers need to rethink the role value plays in their offer. Aldi and Lidl’s approach has allowed consumers to buy good-quality, low-cost food and this has spearheaded a major shift in the way shoppers think about value.

There has always been a low level of trust around quality in value in UK supermarkets. Elsewhere, we have become accustomed to - and even enjoy - shopping at lower-cost retailers in other sectors, particularly within fashion and furniture.

The successful supermarkets of tomorrow will reassure consumers on value and quality, and forge emotional connections that make people enjoy the experience and keep them coming back for more.
