At the presentation of the monthly report card of Ministry of Home Affairs, Home Minister P Chidambaram was asked by a reporter about the details of threats being faced by the Trinamool Congress supremo as claimed in an article on her in US daily Washington Post.
"We have no information," pat came the reply from Chidambaram.
On being pressed further how it was possible for the Centre to be unaware of the magnitude of the charge being levelled by a state Chief Minister, the Home Minister smiled and said "I repeat we have no information."
Mamata recently launched a tirade against her arch rival CPI-M, accusing her Marxist political opponents of plotting with the Maoist rebels to discredit and kill her, in league with Pakistan's intelligence agency and financed by North Korea, Venezuela and Hungary.
"They have given me the death sentence, and every day they are spreading this superimposed photo, on Facebook, on Internet or in the e-mail, through some false, camouflaged name," she had told the US daily when asked about the arrest of a Kolkata professor who had mocked at her in a cartoon.
CPI-M had dismissed the allegation as "ridiculous" and said the party will examine whether it merited a defamation suit against Mamata.
Rejecting the allegation, CPI-M leader Sitaram Yechury had said there cannot be anything more ridiculous than Mamata making such a claim.
