Sir Adrian and Sir John Swire and family

Profits rose by 39.4% to £244m on £2.3 billion sales in 2005 at John Swire, the Hong Kong-based industrial empire. Sir Adrian, 75, above, and Sir John Swire, 80, are no longer on the board but here represent the family, which controls 63% of the group. We value the family stake at £1,500m. Other wealth adds £100m.
