Russia's capital Moscow has been named as the world's most expensive city for expatriate staff to live for the second year in a row. London climbed three places to second in Mercer Human Resource Consulting's 2007 Cost of Living study. Asian cities Seoul, Tokyo and Hong Kong completed the top five. Paraguay's capital Asuncion was the cheapest.The report measures the cost of 200 items such as housing, clothing and food in 143 cities on six continents.

The high cost of accommodation and a favourable exchange rate against the US dollar were the key factors behind Moscow's continued dominance of the annual cost-of-living survey.
