Warner Music boss Lev Blavatnik has topped the 2015 Sunday Times Rich List, with a £13.17 billion fortune.
He replaces Indian-born brothers Sri and Gopi Hinduja, who are now worth £13bn.
The Rich List showed that the collective wealth of the UK's richest 1,000 individuals has more than doubled to £547bn over the past 10 years.
There are now 117 billionaires on the list, up from 104 last year. Eighty of them live in London.
Chelsea Football Club owner Roman Abramovich just makes the top 10 with a fortune of £7.29bn, down £1.23bn from 2014.
The Queen, which topped the first list in 1989 and has featured in every one since, fell out of the top 300 for the first time.
