The Hinduja brothers with estimated wealth of around $14 billion have emerged as the 66th richest, and the only Britons on the list of the world's top 80 billionaires analysis by an Oxfam study that was released in Davos at the World Economic Forum. The numbers based on the rich list compiled by Forbes in March 2014 and data from Credit Suisse, indicate that the London based entrepreneurs are now the richest Britons in the world. Their Hinduja Group conglomerate has worldwide interests that range from automobiles and banking to real estate and IT. The list is topped by Microsoft founder Bill Gates and includes Mexican businessman Carlos Slim Helu and serial investor Warren Buffet. Oxfam has called on world leaders including those gathered at the World Economic Forum Annual Meeting in Davos to address the factors that have led to the current inequality status.
