TMC secretary-general Partha Chatterjee refuted the state BJP's allegation that she had attended a meeting which endorsed the formation of the NIA while she was an MP.
"In every incident the opposition is trying to link up Mamata Banerjee. Campaign to malign her is going on after failing to counter her politically," Chatterjee, who is also the state's education minister, told a press conference here.
Alleging that attempts were made to kill Mamata Banerjee during the erstwhile Left regime, he said, "The CPI(M) could not tackle her, so a campaign is going on to malign her.
He countered state BJP president Rahul Sinha's comment that Mamata attended the Parliamentary Standing Committee meeting on NIA when she was a member of Parliament".
"Let them provide the documents in support of their contention. The Opposition is trying to fish in troubled waters," he said.
Sinha had alleged that Banerjee during her tenure as an MP was a member of the Parliamentary Standing Committee of Home Affairs and was present at one of its meetings in 2007 which took the decision to set up the NIA.
