Nationalist Congress Party chief Sharad Pawar on Wednesday scotched speculation of forming a government with the Shiv Sena , saying his party will work as a "responsible Opposition".Addressing a media conference in Mumbai, Pawar said it was up to the BJP and Shiv Sena to form the government, and that the Congress and NCP would sit in the opposition.“The mandate from people is for the BJP and Sena to form the government. The two parties have been together for the last 20 to 25 years in an alliance. We are confident that they would be able to form govt in next two to three days,” Pawar said.The NCP chief added, " The Congress and NCP have been mandated by the people to sit in opposition. We will work as opposition responsibly. To solve the issues in the state, the BJP and Sena should come together and form the government.”Pawar said the Congress and NCP are allies and that they would take a decision jointly, but added that he was not aware of the Congress stand on the issue.He however added he doesn't "see the possibility of cong and NCP forming government as we do not add up to even 100 seats."On being asked about the claim of Sena leader Sanjay Raut who said the Sena has claimed the support of 170 MLAs, the NCP chief said, “ I have no information on how he has got these figures.”He also claimed that Raut had not given him any proposal on government formation when they met a few hours earlier, but that they discussed "upcoming issues in the Rajya Sabha session where they could take a similar stand".The NCP chief taunted the Sena saying that even while it claimed being "destroyed" because of its alliance with the BJP, both the parties still fought the elections together.In response to a question he also said he maintained that he sticks by his stance that in future anything could happen. The NCP chief did not see the possibility of President’s rule in state and said that the BJP had just talked about it to put pressure on the Sena.Results of the state polls were declared on October 24. but there has been no headway in government formation after that.The BJP, which won 105 seats, and the Shiv Sena, which bagged 56 seats, are locked in a bitter tussle over sharing of the chief minister's post and ministerial portfolios in the new government. They won 161 seats together in the 288-member House, much above the halfway mark of 145. The NCP won 54 seats while the Congress got 44 seats.
