His taste for glamour is reflected in his business line-up, which includes theatre chain and production firm Reliance MediaWorks, and Reliance Broadcast Network Ltd, which has a 50-50 tie up with a unit of US network CBS Corp for TV channels in India.
He is also no stranger to the corridors of power.
He makes a weekly visit to New Delhi and was elected as an independent member of Parliament in June 2004, with backing from the leftist Samajwadi Party.
He resigned in March 2006, as did Congress party leader Sonia Gandhi, in a controversy over MP's holding profit-making positions, citing the need to uphold propriety in public life.
