Mukesh Ambani is the founder and chairman of oil and gas giant Reliance Industries, named among India's most valuable companies.

Ambani is estimated to have a net worth of $85.5buillion, according to his profile in Forbes.

Reliance was founded by his late father Dhirubhai Ambani, a yarn trader, in 1966 as a small textile manufacturer and after his father's death in 2002, Ambani and his younger sibling Anil divided up the family empire.

Ambani's firm Reliance Retail snapped up UK toy retailer Hamleys for an undisclosed sum in 2019 and it is reportedly considering the purchase of ailing department store brand Debenhams.

Reliance Retail has raised billions of dollars this year from the sale of stakes, including a $750million (£578milliom) one to global investment business KKR.

According to Forbes, Reliance sparked a price war in India's hyper-competitive telecom market with the launch of 4G phone service Jio in 2016. During the Covid-19 lockdown, Ambani raised more than $20 billion selling a third of Jio to a string of investors,including Facebook and Google.
