New Delhi: Congress on Monday accused BJP of doing a ‘U Turn’ and ‘double-speak’ over the Indo-US civil nuclear agreement questioning why it had opposed the measure when UPA government was pushing for the deal.

The reaction by Congress came as India and the US reached a breakthrough on the stalled civil nuclear agreement by agreeing on commercial cooperation and decided to take defence cooperation to a new level including on upgrading domestic defence industry and advanced technologies.

"Another U Turn by BJP. Now taking credit for the very Amendments in the Nuclear Bill, which they opposed! Masters of U Turns and Double Speak," party general secretary Digvijay Singh tweeted.

Congress President Sonia Gandhi's political secretary Ahmed Patel had last night said on Twitter, "For 10 years BJP opposed nuclear-deal.Today before they claim credit let it be known what a destructive opposition they have been #Uturn.." Accusing BJP of "political chicanery" on the matter, former Information and Broadcasting Minister Manish Tewari tweeted, "BJP said Indo-US Nuclear Deal compromised India's sovereignty. If that is true, why is BJP bending over backwards to operationalise it now?

In another tweet, Tewari said,"Political Chicanery- after bringing no confidence on the Nuclear & denigrating democracy, BJP finds it as the only peg to hang their coat on".

Congress MP from Haryana, Deepender Hooda posted the purported statements of BJP veteran L K Advani on the Indo-US nuclear deal to hammer home the point. "Advaniji, Lok Sabha July21,08:"IndoUS Nuclear Deal is detrimental to India,& so we are going to bring this Gov down"& 6yrs later :) next-FDI?","he tweeted.
