LONDON: Tesco, the supermarket chain, is the UK's most valuable retail brand, and is worth some $10.6bn on this measure, research by Interbrand has found.

The Best Retail Brands report from the brand consultancy ranked the top 15 UK retail brands by brand value, as well as the top retail brands from eleven other countries.

Tesco was a clear leader in the UK, with a valuation 65% greater than its nearest rival, Marks & Spencer, although this had slipped marginally from the previous year.

Boots, the pharmacy chain, was the most improved brand, adding 16% to its value to reach $3.3bn.

A third of the list were new entrants, including ASOS, the online fashion retailer, B&Q, the DIY store, John Lewis, the department store, The Body Shop, a cosmetics retailer, and Primark, a discount fashion store.

Several themes emerged, including the growth of online shopping. Not only did ASOS enter the top ten, the first time an online retailer has done so, but all retailers have focused on multichannel strategies.

"Investment in improving the overall shopping experience across platforms has been evident with many stores upgrading online and offline channels," said the report.

The brands that succeed have four things in common, the study found. They monitor customer's changing needs; they build a culture of efficient decision-making; they understand that the consumer experience extends beyond the store; and they continuously optimise, scale and measure.

"Outstanding retail brands, such as those on our list, are marked by their ability to transform the ordinary into the desirable", said Jez Frampton, Interbrand's Global Chief Executive Officer.

"It is these exceptional brands that start new conversations, innovate new models and inspire us all to participate in the cultural experience we call shopping."

In the other countries considered, Carrefour was top in France, Aldi in Germany.

In the Americas, Walmart headed the US list, while Lululemon led in Canada, Oxxo in Mexico and Natura in Brazil.

Leaders in Asia Pacific included Uniqlo in Japan, Suning in China, Lotte Department Store in South Korea, FairPrice in South East Asia and Woolworths in Australia.
