Bill Gates has been declared the richest man in the world for the 16th time, by Forbes.

This year's rich list features a record 1,826 billionaires across the world, 197 of them women (29 self-made).

Included in the list for the first time are the two co-founders of taxi app Uber - Travis Kalanick and Garrett Camp - and the first person they hired, Ryan Graves.

Kalanick and Camp have a net worth of $5.3billion (£3.4billion) each, while Graves, who answered a job advert on Twitter five years ago with the words "hire me :)" is now worth $1.4billion (£0.91billion).
