NEW DELHI (Agencies) - India's embattled coalition government survived a chaotic parliamentary confidence vote in Lok Sabha Tuesday, clearing the way for it to forge ahead with a civilian nuclear energy deal with the United States. The emphatic victory has ended the political uncertainty. Indian Prime Minister Manmohan Singh won the backing of 275 deputies against 256 who opposed his Congress-led government, mainly left-wingers and Hindu nationalists, speaker Somnath Chatterjee said at the end of a raucous session. The comfortable margin of the win was made possible by the cross voting of 12 MPs from the NDA, sources say. BJP chief LK Advani informed the media that seven MPs from the BJP ranks cross voted in favour of the government. Two members from TDP also voted in favour of the government. One BJD MPs Harihar Swan who had also voted in favour of the government has already been expelled. Another five BJP members abstained from voting. The names of those who abstained are Chandrabhan Singh, Manorma, Haribhan, Manjunath And Sangalina. One member of Akali Dal also abstained and the party has sought an explanation from him. Another five BJP members abstained from voting. One member of Akali Dal also abstained and the party has sought an explanation from him. The result came after a tense hand-count of some votes that apparently were not properly recorded by machine, and a furore over Opposition allegations that the ruling coalition paid out large sums of cash in bribes to ensure its win. The day was marred by high drama when BJP members shocked the House displaying bundles of currency notes. Charges and counter-charges over the bribery allegations disrupted proceedings for over two hours with the Opposition members not allowing Prime Minister Manmohan Singh to make his customary reply winding up the two-day debate that was often acrimonious. In his six-page reply, which was laid on the table, the Indian Prime Minister hit out at the Left parties, saying "They wanted me to behave as their bonded slave." "They wanted a veto over every single step of negotiations which is not acceptable," he said with regard to the negotiating processes he wanted to undertake with the International Atomic Energy Agency and the Nuclear Suppliers Group before operationalising the nuclear agreement. He said, "I have often said that I am a politician by accident....... whatever I have done in this high office I have done so with a clear conscience and the best interest of my country." M Jagannath of the TDP, who apparently defied the party whip, came to the Prime Minister soon after the vote and congratulated him. Later, he was seen seated in the Congress benches before the result was officially announced by the Speaker. The Indian Prime Minister hugged Rahul Gandhi who made a brief speech hailing the Prime Minister's initiative on the nuclear deal. As Sonia Gandhi beamed in relief, Pranab Mukherjee was also the centre of attraction for the UPA MPs. CPI-M member Varkala Radhakrishnan was the lone Opposition MP to move to the treasury benches to congratulate the Prime Minister. Hitting back at L K Advani for levelling charges of incompetence against him, Prime Minister Manmohan Singh asked the BJP leader to do some "introspection" over his role when Gujarat was burning and during the Kandahar hijack crisis. Replying to the debate on the trust vote in the Lok Sabha, he also asked "our friends" in the Left Front to ponder over the company they were forced to keep because of the "miscalculations" by "their general secretary", an apparent reference to CPI-M general secretary Prakash Karat. In a no-holds barred onslaught at the beginning of his speech, Manmohan said Advani had to "atone for his sins" suddenly decided to visit Pakistan and there he discovered the "new virtues" in Jinnah. "This has sent an important message to the world that India is ready to take its rightful place in the comity of nations," the Indian Premier told reporters, flashing a victory sign and smiling as he emerged from parliament building. "This government has an absolute majority and the confidence to go forward," Finance Minister P Chidambaram said, hailing a victory for what he said was the government's ambitious agenda to modernise and reform India. "Now we have crossed a major bridge that is the Indo-US civilian nuclear deal. Now, we will move ahead on economic and social reforms." In what was seen as a last-ditch attempt to bring down the government, three BJP MPs took to the floor waving bundles of cash worth Rs30m that they said they had been paid for their votes. "Manmohan Singh's office has turned into a mart of corruption, where MPs are bought and sold. So much money has changed hands that it's reached a new level of corruption in India," senior BJP official Vijay Kumar Malhotra told AFP. "But ultimately we are the gainers, and we will win the next general election," which is due by May 2009 at the latest, he said. The Revolutionary Socialist Party, one of the four left-wing parties that forced the vote, said the government's win had "blackened" the face of Indian democracy. "We do not recognise this as a victory. They won because of intense horse-trading," fumed party leader T J Chandrachoodan. Officials in parliament said Chatterjee had called in New Delhi's police chief to investigate the bribery claims. The speaker also said the furore was a "sad day in the history of parliament." Meanwhile, Prime Minister Syed Yousuf Raza Gilani on Tuesday congratulated his Indian counterpart Dr Manmohan Singh on taking the vote of confidence from Lok Sabha (Indian Parliament).
