Britain's wealthiest people are richer than they have ever been, with a combined fortune of £518.9 billion ($874 billion) — equivalent to a third of the nation's gross domestic product, according to an annual study.
The Sunday Times Rich List for 2014 shows that the 1,000 richest men and women have surged to new heights, with their combined wealth rising by 15.4 percent on last year's total of £449.6 billion.
They include TV chef Jamie Oliver, former Tesco supermarket boss Terry Leahy and, in the under-30s list, "Harry Potter" star Emma Watson.
"I've never seen such a phenomenal rise in personal wealth as the growth in the fortunes of Britain's 1,000 richest people over the past year," said Philip Beresford, who has compiled the list since 1989.
Last week, the first part of the Rich List found that the number of billionaires living in Britain had risen to more than 100 for the first time, with Indian-born brothers Sri and Gopi Hinduja the country's wealthiest people, with a combined £11.9 billion. They replaced Russian business magnate Alisher Usmanov at the top after his fortune fell to £10.6 billion.
Only three of the top 20 are British, with publishers and property developers David and Frederick Barclay the only self-made billionaires in this group.
The richest Briton, the Duke of Westminster, is ranked 10th with a property-based fortune of £8.5 billion.
In the list of the 50 Young Rich, who are age 30 and under, 24-year-old "Harry Potter" star Watson is now worth £30 million, up by £3 million.
