TWO Oxfordshire billionaires feature among the biggest risers and fallers in this year's list of Britain's richest people.

Sir Anthony Bamford and family live at Daylesford, near Chipping Norton, where Lady Bamford's farm shop now sells luxury clothes and household goods. They boast a fortune of £1,950m - up £650m from 2007.

The Bamfords, listed at 34 (up from 43rd) inherited money made by Sir Anthony's late father Joe, who founded the JCB digger group in 1945 (named after his initials).

Sir Anthony also appears as Britain's 18th highest political donor, having given the Conservatives £161,589.

But Sir Richard Branson, who has a home in Kidlington, is 13th biggest faller in The Sunday Times list of Britain's richest 1,000 people. He drops to 20th from 11th last year, with wealth estimated at £2,700m, £400m less than in 2007, when he fell out of the top ten.

Hotelier and former chairman of Oxford United Firoz Kassam, who owns Heythrop Park, near Enstone, has also fallen down the list, from 263 to 297, though his wealth is unchanged at £275m. His plan to redevelop Alexandra Palace in London is said to be embroiled in legal wrangles.

Booksellers and publisher Toby Blackwell, and his nephew Nigel Blackwell, also fell - from number 249 to 303 - though again their estimated assets stay the same at £249m.

Toby Blackwell has given £5m to Oxford's Bodleian Library, next to the original Blackwell's Bookshop, founded in 1879 in Broad Street.

A newcomer in the list is Iain Dorrity, chief executive of solar panel maker PV Crystalox Solar, based at Milton Park, near Didcot, whose wealth is estimated at £71m.

Syrian-born Wafic Said falls from 65 to 71. He has a 300-acre estate at Tusmore, near Bicester, and a fortune estimated at £1bn. In 1998, he donated £20m to Oxford's Said Business School.

Among the risers are Stewart Milne and family, who own Stewart Milne Timber Frame Systems in Witney, at number 214, up from 251, with £294m.

Mining tycoon Roddie Fleming, who lives in West Oxfordshire, is 35th with £1,900m, and foreign exchange dealer Urs Schwarzenbach is 88th with £852m. Mr Schwarzenbach bought his house near Henley from Sir Martyn Arbib, who 239th with £370m.
