A west London-based businessman has topped The Sunday Times' Rich List with an estimated fortune of £13.17 billion.

Ukrainian born Len Blavatnik, who owns a £200million 13-bedroom, grade II listed house in Kensington Palace Gardens, jumped up four places from last year after seeing his wealth rise by more than £3 billion.

The Warner Music Group owner beat a total of 117 billionaires on the list, up from a total of 104 last year.

Mr Blavatnik took over top spot from brothers Sri and Gopi Hinduja, who were nudged into second despite their fortune rising by £1.1 billion to £13 billion.

Despite the global recession, the figure has more than doubled since £249.615 billion was recorded in 2005.
