This is what Tesco think and to be fair they don't get it wrong that often - from their 2009/10 accounts:
In Turkey, whilst we slowed our rate of new store growth, it remained strong enough to offset the like-for-like sales decline, helping us to grow overall sales during the year. With the economy showing early signs of recovery we are planning to resume a faster rate of expansion this year. Turkey remains an important strategic long-term opportunity for us as a large, growing and relatively underdeveloped retail market.
