Tokyo named world's most expenive city

Luanda, in Angola, is second in annual cost-of-living survey as London slips to 25th and Australian cities move up

Tokyo has regained the dubious honour of being the world's most expensive city, where a cup of coffee will set you back £5.25, a newspaper £4 and a litre of milk £2.
The Japanese capital topped the annual cost-of-living survey by the HR consultants Mercer, which ranks cities according to the needs of expatriates. Luanda, in Angola, where more than half the population of 5 million live in poverty and where the Foreign Office advises visitors not to venture out at night, was the second most expensive.
British cities have fallen down the list in recent years, reflecting the weakness of sterling against the US dollar. London was the 25th most expensive city, said Mercer, down from 18th last year and behind every large Australian city and many emerging Asian metropolises
