Sarwar Ahmed, who publishes the list, said: 'Most people on it have increased their wealth, despite the fact that it was a bad year for business on the whole and we were expecting the value of the list to go down. Even taking into account that there are 275 people on the list year instead of 250 like last year, the total value is still £500m higher and there are also 45 new entries. A lot of Asian people have money tied up in property and are much more likely to invest in bricks and mortar than stocks and shares. Around 99% of them do not buy leasehold, only freehold, which underlies the shrewdness they have in investments.'
