HE may have been a colleague of Rajiv Gandhi from his Indian Airlines days, but Satish Sharma has run out of favour with Sonia Gandhi. According to very reliable sources in the Congress, there is no move from 10, Janpath to rescue the former Union petroleum minister, whose deals are being investigated by the CBI. In fact, there is little sympathy for Sharma even within his party. And in the absence of any indication from Rajiv Gandhis widow that he must be helped, the former minister may well have to fight a lone legal battle.
