Roger De Haan and his brother Peter feature twice in the latest survey of the nation’s wealthy.

Peter made his fortune from the sale of his stake in Saga, the over-50s financial services and holiday group, based in Folkestone, in 1999 whilst Roger’s was made from its sale in 2004.

The duo are ranked 110th in the Sunday Times Rich List 2013. Although their wealth is estimated at £800m, the same as last year, the brothers slip from 92nd place in last year’s list.

Through their charitable trusts – their financial affairs are now separate although aggregated for Rich List purposes – they have invested substantial sums in education, the arts, wildlife, welfare organisations and Folkestone.

Roger has injected huge amounts in the Creative Quarter, Folkestone Harbour, Seven Hills Sports Ground and the Marlowe Academy, Thanet. Their generosity places them 43rd in the Sunday Times Giving List, with combined donations in the past year estimated at £16m.

Moni Varma (below), founder of Veetee Rice, based on Medway City Estate, has leapt up the table from 908th (£80m) to 373rd (£212m), largely on the strength of his stated intention to float the company for a possible £200m.

Dartford-born Rolling Stone Sir Mick Jagger climbs seven places from 395th (£190m) to 387th (£200m).

Russian Alisher Usmanov tops the list with £13.3bn for his mining and investment interests. The Duke of Westminster is the highest-ranked Briton at 8th with estimated wealth from his property portfolio of £7.8bn.
