London-based and Kenya-born Ketan Somaia, who had been found guilty of fraud and jailed for eight years last year, was ordered by the Old Bailey court in London to pay up or face a further 16 years in prison.
He was found guilty of nine out of 11 charges of obtaining a money transfer by deception by a jury which noted that Somaia "has to be described as a formidable and serial fraudsman on a truly Olympian scale."
It marked Britain's biggest-ever private prosecution carried out on behalf of the principal victim, entrepreneur Murli Mirchandani.
In another legal first Mirchandani secured 500,000 pounds of public funds to continue his fight to recoup the money he lost in the swindle.

"Mirchandani wants his money back and this hasbeen a long process through a private prosecution and confiscation proceedings which have taken its toll in emotional stress. He just wants to put an end to all that," said Edmonds.
Mirchandani said:"This is a bittersweet victory, my fight for justice has robbed me of fifteen years of my life."
"There are no words to describe the betrayal that my family and I have suffered at the hands of a callous man who claimed to be my friend. While today brings some form of closure, it remains to be seen whether Ketan Somaia will comply with the Confiscation Order or face additional years in prison."
The scam took place between 1999 and 2000 whenhe was president and chief executive of the Dolphin Group of Companies.
He owned an office in Mayfair and a palatial home in an exclusive north London suburb.
He is said to have used his purported wealth and status within the Indian community to persuade Mirchandani to make large payments after promising him high returns.
