Cuddalore(TN), Dec 8 (PTI) Congress Vice-President Rahul Gandhi today alleged a "political vendetta" by the ruling BJP into the National Herald case, and insisted that he will not be cowed down and will continue asking questions to put pressure on NDA at Centre.

Earlier, a combative Sonia Gandhi, invoking the legacy of her mother-in-law and former Prime Minister Indira Gandhi, had asserted that she was not scared of anyone.

"Well I absolutely see a political vendetta. This is the way the Central government functions, the way they think," Rahul, who was here to distribute aid to flood-hit people, told reporters.

Rahul said the government at the Centre thought it could stop him from asking questions "about them" by adopting such "vendetta politics," but "that is not going to happen."

"I am going to keep asking exactly the same questions I have been asking. I am going to put pressure on the government and I will continue to do my job," the Amethi MP said.

While Rahul initially said that he will react on the issue after returning to Delhi where Parliament is in session, he, however later said that there was "political vendetta" on the issue after reporters' repeated queries.

Delhi High Court yesterday rejected the pleas of Rahul and Sonia for quashing the summons against them in the National Herald case.

However, today, they were directed to appear in person on December 19 by a Delhi court which allowed their plea seeking exemption from personal appearance for the day in the National Herald case.
