"The report has been submitted by the committee to chief minister which names a BJP MP besides pointing out laxity of administrative officers," Samajwadi Party's national general secretary Naresh Agarwal said.
"As the role of a BJP MP has also come to the fore, we can say that the party (BJP) has a role in the Saharanpur incident," he said.
The five-member committee headed by UP minister Shivpal Yadav, which inquired into the July 26 violence in the western UP district that left three persons dead, has alleged that local BJP MP Raghav Lakhanpal provoked the rioters which led to attempts to torch shops, according to sources.
Trashing the allegations, Lakhanpal said they reflected the "low level politics" of Samajawadi Party which was trying to "appease" a particular community ahead of Assembly bypolls in Uttar Pradesh.
"It is politically motivated. I have been praised for my efforts to end to the violence and restore peace. The government should have thanked me instead of levelling false allegations," the MP told PTI in Saharanpur.
While the BJP dismissed the report as an attempt by the Samajwadi Party to gain political mileage, BSP supremo Mayawati targeted both Samajwadi Party and BJP, alleging that the two parties were hand in glove in fanning communal violence in the state.
The BSP leader said the "actual facts" are were buried and the report has little meaning.
"BJP and SP are hand in glove. The report has not put forth the actual facts. It has little meaning. We do not accept the report," Mayawati said.
The Congress too reacted sharply saying Prime Minister Narendra Modi should follow his words that communalism will not be tolerated and take up the issue "strictly" with his party men.
Union Home Minister Rajnath Singh said he would not comment as it was a "report of a political party" and he had not seen it.
The report has blamed laxity of some officers and said the government should take stern action against them to give a message to the bureaucracy, Agarwal said.
The committee alleged that the administration became active only after the violence broke out.
As the holy month of Ramzan was going on, the administration should not have allowed any construction at the disputed site or members of opposite community to assemble, the report said.
