So the man who once claimed that food retailing was "easy-peasy" has done it at last. For a long time it looked as if the eloquent 48-year-old resident of Monaco had been daunted by the rigours and perplexities of council planning permissions and supplier contracts.But Sir Stelios Haji-Ioannou has now opened a first low-budget easyFoodstore in gritty London suburb Park Royal, thus making good on his promise to undercut German discounters Aldi and Lidl in the UK. Like a latter-day Freddie Laker, the charismatic Greek-Cypriot billionaire is on a self-appointed mission to give the British people cheaper prices.The story of a guy, whose favourite TV programme is said to be Only Fools and Horses, is well known. After creating the low-cost airline easyJet in 1995 and successfully taking it public five years later, Sir Stelios went on to found easyHotel, easyPizza, easyBus, easyGym etc. under the umbrella of his private investment vehicle easyGroup.A serial entrepreneur will best appreciate the Derek 'Del Boy' Trotter philosophy of "some you win and some you lose". So is easyFoodstore just a good PR stunt, or is Sir Stelios serious? And, if he is, does he have a bat's chance in hell?
