Debenhams, the upscale British department store chain, has decided to open 12 more Sports Direct concessions by August 2016, covering a total of 200,000 square feet, after encouraging tests since last summer at its stores in Bristol, Guildford, Harrow and Portsmouth. The management said there was no relation with the fact that Sports Direct International owns a minority stake in Debenhams. Meanwhile, SDI's major shareholder, Mike Ashley, is said to be backing the £200 million (€270.9m-$302.5m) redevelopment of a former John Lewis site in the Chelsea district of London.
