Shopping is a serious business in London whatever the season—but it doesn’t get much more serious than this time of year. The UK’s capital January sales sees throngs of dedicated shopaholics cram its countless department stores, quirky boutiques and market stalls, keen to get their hands on the latest fashion trends and product offers. But it’s not just domestic spending that’s keeping the tills ringing in London. While the vibrant city’s high-end stores are no strangers to overseas visitors, with those from the Middle East typically spending the most, a surprising new contender has emerged in recent times as a big spender in the international market—Nigeria. Nigeria’s economic growth has averaged about 7.4% annually over the past decade, creating a wealthier Nigerian elite with a large spending power. At the same time, however, robust economic growth has not reduced poverty in the country, with about two thirds of its population living on less than $1 per day.
