| Roxburghe, 51, the 10th duke, has more than 30 years experience running the 65,600-acre Scottish estate he inherited in 1974. Aside from his land and horse racing interests, his assets include Floors Castle in Kelso and valuable fishing rights. With increasing development activity on the estate, including the construction of upmarket homes, and the prospect of a return on shrewd investments including a share in a call-centre firm, we raise our valuation to £80m. |
