Apollo Global Management and TDR Capital are two other private equity groups thought to be looking to buy a large stake in Asda, which parent Walmart has put up for sale. Asda's advisers at Rothschild have received three bids for the grocer, the Times reported. Already in the UK supermarket sector, Sainsbury's ( LON:SBRY ) netted a £95mln profit from redeveloping two stores in south London in partnership with Barratt Developments PLC ( LON:BDEV ), while Tesco ( LON:TSCO ) has developed mixed-use buildings on top of several stores in the capital as part of a plan to potentially generate £400mln from its air rights.
