Terming Congress as a burden on the country, Gujarat Chief Minister Narendra Modi on Sunday said Prime Minister Manmohan Singh was a good man "spoilt by the rot" in the party.

"When Manmohan Singh became the PM, he was a good person, we did not say anything against him. But, because of being with the Congress, he has got spoilt; and if people like Singh get spoilt by the rot in Congress, then we need to remove that rot," Modi said at a public gathering at Vastral on the city outskirts.

"Congress party has become a burden for our country. It has rotted, which is now visible in its public image," he said.

The BJP leader also referred to internal dissensions in the Congress, talking about how Union Finance Minister Pranab Mukherjee and Union Home Minister P Chidambaram were at loggerheads while the Prime Minister had been a just a mute spectator.

Modi said it was eight months since a Centre appointed committee headed by him submitted a report to Singh recommending measures to control price rise but the Prime Minister was yet to see it.

The report, suggesting measures to control high food inflation, had recommended a ban on the futures trading in essential commodities.

"During the meeting of Chief Ministers last year, four committees were formed, of which I headed one. My committee submitted the report eight months ago, recommending steps to control price rise. The Prime Minister had then acknowledged our efforts in preparing the report, but he has not bothered even to open the cover of the report," Modi said.

He said he had asked other leaders to remind the PM of doing something about the report.
