In these cash-strapped times, it's a lucky father who can afford to help his children on to the property ladder.
Especially when the sums involved run into hundreds of millions of pounds.
After buying an £117million mansion near his London home for his son Aditya, steel magnate Lakshmi Mittal has just splashed out a further £70million on a place thought to be for daughter Vanisha.
The combined value of the three properties, which are a few hundred
yards apart in Kensington Palace Gardens, is said to be an astonishing £440million.
