After their 30-minute meeting with the Prime Minister, Yadav and Amar Singh appeared convinced that the nuclear deal is in the interest of the country and said they would try to convince other UNPA constituents on the issue.
The party, whose 39 MPs in Lok Sabha would be crucial for survival of the government if Left parties withdraw support, are likely to announce its decision on supporting the UPA in a couple of days.
The SP leaders said former President A P J Abdul Kalam had on Thursday elaborately explained to them the benefits of the deal and allayed fears about the national sovereignty or foreign policy being compromised.
"We have been opposing it (nuclear deal) as we did not have any new details. But now these new details have come," Yadav told reporters.
Asked whether they were satisfied with the clarifications given by the PMO in a statement two days back, Yadav said "the entire nation would be satisfied."
Amar Singh said the Prime Minister's statement, addressing point-by-point issues, was "quite satisfactory" but the UNPA had decided to consult some "eminent" and "undisputed" scientist who was identified as Kalam.
He pointed out that the "renowned" scientist Kalam, who has worked a lot in the nuclear field, told them that the country will face "no danger or pressure" because of the deal.
Sounding convinced that the deal is in national interest, both Yadav and Amar Singh said "national interest was a priority to them rather than politics".
They, however, insisted that they had given no commitment to the Prime Minister about extending support as they will have to consult other UNPA leaders.
