Kundra, 37, was born into a "simple middle-class" family in London.
About 45 years ago, Kundra's father Bal Krishan was asked by his father to go to London from Ludhiana to "earn some money and send it back to us".
Bal Krishan's first job abroad was in a cotton factory.
Then he went on to work as a bus conductor.
His wife worked in an optician's showroom.
On days when their shifts clashed, his mother would take little Kundra to work and put him in a back seat of a car outside the showroom where she worked. Every three hours she would tend to him, change his nappy, refill his milk bottle and then go back inside to work.
"My two younger sisters and I realised early that our parents were working really hard to keep us comfortably and that we needed to understand the value of money," says Kundra.
In 2004 a UK magazine ranked him the 198th-richest British Asian.
