The number of billionaires living in the UK has topped 100 for the first time ever, according to the 2014 Sunday Times Rich List.
A total of 104 billionaires now call Britain home, with a combined wealth of £301bn between them, which means the UK has more billionaires per head than any other country.
The majority of those are based in London, with the capital home to 72 billionaires. That outstrips closest rival Moscow which has the second highest billionaire population with 48, followed by New York with 43.
Last year, 88 billionaires were living in the UK, worth a total of more than £245bn, according to the Sunday Times Rich List. In 2004, the number of billionaires in Britain was 30, with a combined wealth of £65 billion, it said.
A fortune of £1.7bn is now required to make the top 50 - up from £700m 10 years ago.
Among the new members of the billionaire club is West End producer Sir Cameron Mackintosh, who saw his fortune rise by £175m in the last year and is now worth £1bn.
Sri and Gopi Hinduja,The Indian-born brothers who run the global conglomerate Hinduja Group, saw their wealth rise by £1.3bn in the past year, putting them in the top spot.
Meanwhile Russia's Alisher Usmanov slipped to second place, down from first last year, after losing £2.7bn during the Ukraine crisis.
Philip Beresford, compiler of the annual table and MT contributing editor, said the Russian and Ukrainians at the top of the list had seen their wealth dented by the stand-off with Ukraine. That led to the rouble falling to an all-time low and Russian stocks tumbling.
Most of the billionaires on the list were born abroad, reflecting the lure of London to wealthy international investors.
