Keith Miller, chief executive of Miller Group, was named one of the biggest risers in The Sunday Times Rich List 2006, after amassing a £715m fortune.

Miller and his family's increasing fortune boosted them 20 places to joint 84th in the elite league, compared with the 2005 list which revealed a smaller fortune of £480m.

The money made from the family housing, development and construction business means that Miller is richer than the Queen, Madonna and the Beckhams.

The Scottish-based private company was founded by Miller's father and uncle in 1934, but under his guidance it has grown into a company with a turnover of more than £1bn.

With its roots in Edinburgh, the company is now national but with less influence in the South. Last year Miller led it to its biggest deal when it bought Fairclough Homes for £264m.
