A 10-member delegation of Indian-Americans who lobbied hard in the United States in favour of the India-United States civil nuclear deal, is meeting leaders of Left parties and the Bharatiya Janata Party to impress upon them the benefits of the agreement.

The delegation led by United States India Political Action Committee Chairman Sanjay Puri will meet on Tuesday with Union ministers, and the central leadership of the opposition BJP.

The delegation, comprising top politically active businessmen, is also expected to meet leaders of Left parties and explain to them the potential the deal holds for India's future.

"The deal has a great potential to ensure India's energy security and also benefit its economy," Puri told PTI.

He said the delegation will also try and understand the position of various political parties on the nuclear deal and the reasons for their opposition to it.

The USINPAC has been vociferously lobbying for the Indo-US nuclear deal with key policy makers and office bearers of the American establishment and have provided an impetus to the process of the deal getting through in the US Senate.

Puri, however, said USINPAC wants to steer clear of any interference in the decision-making process in India.

The USINPAC chairman met US Ambassador to India David C Mulford on Monday afternoon as also some key officials in the prime minister's office.

The left parties, who believe that the deal compromises India's independent foreign policy, expect the government to tell them that the deal is off, while the prime minister has been saying that he is hopeful of a consensus in favour of the agreement.
