Spanish multi-billionaire, Amancio Ortega has just knocked Bill Gates off his podium as the world's richest man. In a matter of hours, Ortega earnt a whopping $4 billion yesterday, all thanks to a hike in the shares of Zara's parent company Inditex, which is partly to thank for his new rank in the economic market. 

Ortega, who launched Zara when he was 40 has since gone from strength to strength amounting a net worth of $79.8 billion. 

Zara stores are found across the Middle East.
