Former Home Secretary G K Pillai's remarks on affidavit regarding LeT links of Ishrat Jahan on Friday triggered a political war of words with Congress questioning the timing of his claims and alleging that he was only parroting the ruling BJP's words.

Asking the Congress to come clean on the issue, BJP praised Pillai for his "boldnesss" after he on Thursday claimed that the affidavit submitted to the Gujarat High Court in 2009, when UPA was in power, about LeT links of Ishrat Jahan and her accomplices, who were killed in an alleged fake encounter in 2004, was changed at the "political level".

Questioning the timing, Congress leader Renuka Chaudhury asked why Pillai made these claims now.

"How to establish political pressure... it is unfortunate.... Why say it today," she said.

Another Congress leader Pramod Tiwari said had the former Home Secretary made the statement then, it could have carried "more credibility".

"Now, he is parroting what BJP said. Who would believe him," he said.

The then UPA government had submitted two affidavits - one that the four, who were killed in an alleged fake encounter, were terrorists and the second saying there was no conclusive evidence - within two months in 2009.

But senior BJP leader and Parliamentary Affairs Minister M Venkaiah Naidu said it is time Congress made its stand clear on Ishrat and Parliament attack convict Afzal Guru.

"A traitor, he is responsible for attack on Parliament...," Naidu said referring to former Home Minister P Chidambaram's remarks that Guru's case "was perhaps not correctly decided".

Asked whether government would take 'action' against Pillai for his remarks, Naidu said on the contrary "we should appreciate for his boldness." 

JD(U) General Secretary K C Tyagi said the remarks of Pillai were "non-serious" as bureaucrats "do anything for transfers and postings".

Former Home Secretary and BJP MP R K Singh said Jahan was "very much" part of LeT plot. He refused to comment on the changed affidavit saying he was not the Home Secretary then.
