India is not depending solely on diplomacy to win the United States Congress' backing for its civilian nuclear cooperation deal with Washington but also taking the help of lobbyists, a media report said on Monday.

Time magazine reported that in the last fall, long before the visit of President George W Bush [Images] to India, the Indian Embassy in Washington had signed up two lobbying firms to 'sell the deal'.

The Embassy has signed a $700,000 contract with Barbour, Griffith and Rogers, an outfit led by Robert Blackwill, US ambassador to India from 2001 to 2003, it said.

Besides, the Embassy is also paying $600,000 to Venable, a firm that 'boasts' of former Democratic senator Birch Bayh of Indiana as its point man.

The deal, under which India would get uninterrupted supply of fuel for civilian nuclear power reactors which it puts under international safeguards, was signed during President Bush's recent visit to New Delhi and has to be approved by the US Congress.
