Four close-knit siblings, Srichand, Gopichand, Prakash and Ashok, control the Hinduja Group, a far-flung multinational empire with businesses ranging from trucks and lubricants to banking and cable television. The group commissioned its much-delayed 1,040 megawatt thermal power unit in south India in July. The brothers are expected to open London's first Raffles Hotel in the historic Old War Office building in Whitehall they bought 2 years ago with a Spanish group.
