The collective wealth of the richest 1,000 people in the UK has jumped to £412 billion, up from £99 billion in 1997, a 316 per cent rise, according to the Sunday Times Rich List. The total wealth of the nation has only doubled in this period says the annual survey of the UK's wealthiest individuals. Even since Gordon Brown took over as Britain's Prime Minister, the wealth of the top 1,000 people in the UK has risen by 15 per cent, according to the survey. Philip Beresford, the list's compiler said: "Having a friendly Labour government has almost been better than having a Tory one; it has neutered politicians on the left." There are now 75 billionaires based in the UK, according to the list. The list is headed up by steel Magnate Laksmi Mittal who fortune has risen to £27.7 billion to £19.25 billion, up 44 per cent, on the back of increased demand for steel. Second on the list is Roman Abramovich, the owner of Chelsea football club, with £11.7 billion Of the top 20 UK-based billionaires, only six were born in the country, including number three on the list, the Duke of Westminster, with £7 billion, Sir Philip and Lady Green, with £4.3 billion, the Earl of Cadogan with £2.9 billion, trader Joe Lewis with £2.8 billion and Sir Richard Branson whose wealth, the Rich List estimates to have fallen £400 million to £2.7 billion in the last year. New entries include Leonard Blavatnik, a Russian oil billionaire, at 11th with £3.9 billion and mining company owner Vladimir Kim with £2.9 billion. Heading the UK's richest women is Kirsty Bertarelli who, as well as marrying biotech billionaire Ernesto Bertarelli, was Miss UK in 1988. The couple are this year ranked sixth with a fortune of £5.65 billion. Ms Bertarelli is way ahead of the Queen who comes in at number 264 with £320 million. Although the first Rich List, in 1989, put the monarch at number one, with a fortune estimated at £5.2 billion, this included the royal art collection which, is now accepted, she looks after on behalf of the nation. According to the list, the Queen's investment portfolio is this year down £20 million to £100 million. At the top of the list philanthropists is activist fund manager Christopher Hohn of The Children's Investment Fund, whose recent donations amount to £235.8 million, well over twice his remaining fortune. Harvey McGrath, ex-chairman of London-listed hedge fund manager, Man Group, is listed at 39th on the giving list, having given £4 million of his £176 million total wealth in the last 12 months. Mr McGrath was a headline speaker at WealthBriefing's Breakfast Briefing on philanthropy which was held at the end of last year.
