Carlos Slim Helu holds the title of the world’s second richest man having lost the world’s richest spot to Bill Gates in May 2013. The biggest chunk of Slim’s fortune lies in telecoms. He also owns mining, financial, industrial and real estate companies, plus a stake in the New York Times. In 2012 he added soccer to the mix, buying into Mexico’s Leon and Pachuca clubs and Spain’s Real Oviedo. In February, Slim and Bill Gates announced they were funding research to reduce hunger and support innovation for farmers in the developing world.
