MUSK NO LONGER WORLD RICHEST MAN.

Elon Musk has slipped down the list of the world's billionaires to second place as Bernard Arnault takes the top spot

Musk, 51, who bought Twitter for $44billion, last year earned the top spot on the Forbes World Billionaires list, which reckoned he had a net worth of $216bn.

CNN reported that Arnault was able to overthrow Musk in the annual list after his net worth grew more than $50bn to $211bn, as Musk's net worth slumped to $180bn, $39bn less than it was last year, thanks to the purchase of Twitter which was funded by Tesla shares.

Frenchman Arnault first appeared on Forbes' billionaires' list in 1997, when he was worth just $3.6bn, with his wealth subsequently growing due to the 70 luxury brands he owns.
