Finance Minister P Chidambaram on Friday rejected allegations of horse trading and corporate money power playing a role in the United Progressive Alliance government's trial of strength.

He also made it clear that the government would not abdicate its responsibility in managing the economy saying it would be in office till the next elections.

"It is all entirely speculative. It is a creation of the media. I don't think corporates have any role in either saving or defeating the government. I think it is an exaggerated notion of corporate power," he told PTI.

He was replying to queries on media reports about the influence of the corporates and their money power in the ensuing vote of confidence in the Lok Sabha on July 22.

He also deplored CPI leader A B Bardhan's allegation that UPA was buying MPs for Rs 25 crore (Rs 250 million) each for survival and was using the corporates in this terming it as 'outrageous'.
