Luanda in Angola is the world's most expensive city for expatriates for the second year running, according to a new survey.
Mercer's 2011 Cost of Living Survey ranks worldwide cities by how expensive they are to live in for ex-pats. After Luanda in the number one spot, Tokyo is ranked the second most expensive city, with N'Djamena in Chad in third place.
These are followed by Moscow, Geneva and Osaka in fourth, fifth and six places respectively.
London is ranked the 18th most expensive city for ex-pats to live, one place lower than the same survey last year. Other UK cities have all moved up the list. Aberdeen jumped from 149 to 144, Glasgow from 155 to 148, Birmingham from 158 to 150 and Belfast from 182 to 178.
