Born in Pakistan to a middle-class family, Khan moved to the US when he was a teen to study. He reportedly slept in a YMCA hostel that cost $2 (£1.60) a night, washing dishes for $1.20 (95p) an hour to make ends meet.
But the businessman’s hard work paid off. He bought auto parts firm Flex-N-Gate in 1980 after previously working at the company and designing a one-piece truck bumper that was hugely successful. Today, he owns US NFL team the Jacksonville Jaguars, and British soccer team Fulham, and is worth a staggering $12 billion (£9.4bn).
