Four years ago Yevgeny Chichvarkin was the king of Russia’s retail market. A backstreet kid with a knack for sales, Mr Chichvarkin co-founded Yevroset, a mobile phone store, in 1997 at the age of 22. With just $5,000 (€3,862, £3,227) in start-up capital, he soon turned it into Russia’s biggest handset retailer.
