He is the younger son of construction tycoon Pallonji Shapoorji Mistry, who holds about an 18 per cent stake in Tata Sons, making him the single largest shareholder in the $100 billion conglomerate.
Mr Mistry is married to Rohika Chagla, the daughter of lawyer Iqbal Chagla. He has an elder brother - Shapoor Mistry and one of his sisters is married to Noel Tata, Ratan Tata's half-brother. He is an avid golfer.
