While many daughters and grand-daughters of the world's wealthiest would never actually inherit a billion-dollar fortune, Indian-origin steel tycoon Lakshmi Mittal's daughter Vanisha Mittal Bhatia has emerged as the potentially richest among those standing to inherit a fortune, according to US business magazine Forbes.

Vanisha is followed by Isha Ambani, the richest resident Indian Mukesh Ambani's only daughter, at the second rank, and another Indian billionaire K P Singh's daughter Pia Singh at the third position in the Forbes list of the world's likely- to-be richest heiresses.

Mittal was ranked as the fourth richest person in the world in March when Forbes published its annual rich list, followed by Mukesh Ambani at the fifth rank.

"Perhaps best known for the USD 60 million wedding her father threw for her in 2004, she (Vanish) now serves as a director on the board of dad's USD 103 billion steel company, ArcelorMittal," Forbes said.

"Her corporate involvement and small family -- she has only one brother -- puts her in good stead to inherit a sizable chunk of her father's fortune," the magazine noted.

About 16-year-old Isha, it said that Mukesh Ambani's only daughter is ‘just a teenager but already has her own stake in the family's Reliance Industries, worth about USD 80 million’.
