Arvind Kejriwal today rubbished Congress leader Digvijay Singh's claim that he had lobbied for an entry into Sonia Gandhi-led National Advisory Council seven years ago, saying he has never approached anyone for this.

"I have never approached anyone for NAC. I never had any desire for being a member of NAC," Kejriwal told PTI when asked about Singh's claims that he along with Swami Agnivesh had met him for help in getting into NAC in 2005-06.

When contacted, Agnivesh said the meeting is said to have happened six-seven years ago and he does not remember any such meeting.

"The issue which Singh raised happened in 2005-06. Time has passed. I don't remember whether I met him with Kejriwal or not," Agnivesh said.

In a letter to Kejriwal, the AICC General Secretary has described the activist as a "self-serving ambitious megalomaniac" having "streak" of Hitler in him. Singh alleged that Kejriwal wanted him to recommend his name for being made a member of the NAC.

Yesterday, Kejriwal said Singh's letter describing him as a "self-serving ambitious megalomaniac" does not merit a response and it only showed that Congress party was "completely rattled and baffled".

"Digvijay's letter to me does not merit a response. Congress seems to be completely rattled and baffled. That is apparent from Digvijay's letter. Digvijay seems Congress' last resort," Kejriwal had said.

Responding to Singh's remarks, Kejriwal's close associate Kumar Vishwas said, "We have only one thing to say to him. Get well soon."
