Reacting to the FIR filed against Amar Singh, Samajwadi Party chief Mulayam Singh Yadav on Friday said it was a conspiracy to malign the party general secretary and cine star Amitabh Bachchan at the "instance" of UP Chief Minister Mayawati.
The FIR was based on malafide intentions, he said and demanded immediate intervention of Prime Minister Manmohan Singh in bringing the "conspirators" to book.
The development showed state government's frustration over growing political stature of Amar Singh and widespread popularity of Amitabh Bachchan and was aimed at "maligning" them, Yadav said.
This would not be accepted at any cost, he said alleging Mayawati was behind the conspiracy to malign Amar Singh and Amitabh Bachchan.
"Had there not been Chief Minister's tacit approval, police would have taken action against the conspirators behind the FIR," he said.
An FIR has been filed in Kanpur against Amar Singh and his wife for alleged financial fraud amounting to about Rs 500 crore, a charge dismissed by Singh as "conjecture".
