Hazare, who held the one-and-a-half hour meeting at BJP headquarters here, said the talks were "good and fruitful".
"In our discussions, the drafts of the Jan Lokpal Bill and the government draft were discussed. It was felt that there is a need for more debate for a strong Lokpal Bill," Hazare said.
"We have requested the BJP that when the Bill comes up in Parliament its leaders like Arun Jaitley, Advani and Sushma Swaraj should argue strongly for it and they have agreed," Hazare said.
He said, "We have got a good guidance (from BJP) on how this Bill should be. The talks were good and fruitful." Hazare was accompanied by civil society activists Arvind Kejriwal and Kiran Bedi.
The BJP team comprised of L K Advani, Sushma Swaraj, Arun Jaitley, M M Joshi, Jaswant Singh, Yashwant Sinha, M Venkaiah Naidu, S S Ahluwalia, Ananth Kumar, Ramlal and Ravi Shankar Prasad.
Both the sides maintained that the issue of bringing the Prime Minister within the ambit of the Lokpal was not discussed.
The main concern voiced by the Opposition while agreeing on the need for a Lokpal was that persons with a clean image should be appointed.
The questions raised by BJP were also about Constitutional immunity to the MPs in Parliament as ensured in Article 105.
"We heard Anna Hazare and his team and gave them all respect. We sought some clarifications. We have assured them that we want an effective Lokpal. We will form an opinion on the issue after holding a party meeting and talking to the NDA," Prasad, who is chief spokesperson of the BJP, said.
