The 85 richest people on the planet have accumulated as much wealth between them as half of the world's population, political and financial leaders have been warned ahead of their annual gathering in the Swiss resort of Davos.
The tiny elite of multibillionaires, who could fit into a double-decker bus, have piled up fortunes equivalent to the wealth of the world's poorest 3.5 billion people, according to a new analysis by Oxfam. The charity condemned the "pernicious" impact of the steadily growing gap between a small group of the super-rich and hundreds of millions of their fellow citizens, arguing it could trigger social unrest.
It released the research on the eve of the World Economic Forum, starting on Wednesday, which brings together many of the most influential figures in international trade, business, finance and politics including David Cameron and George Osborne. Disparities in income and wealth will be high on its agenda, along with driving up international health standards and mitigating the impact of climate change.
Oxfam said the world's richest 85 people boast a collective worth of $1.7 trillion (£1trn). Top of the pile is Carlos Slim Helu, the Mexican telecommunications mogul, whose family's net wealth is estimated by Forbes business magazine at $73 billion. He is followed by Bill Gates, the Microsoft founder and philanthropist, whose worth is put at $67 billion and is one of 31 Americans on the list.
Other well known names include the business magnate Warren Buffett, whose estimated worth is $53.5 billion, and Larry Page, the co-founder of Google, with $23 billion.
