"Anna is too dear to us. I have deepest respects for him. After launch of our party on November 26, we will not use IAC name," Mr Kejriwal tweeted on Sunday.
Earlier in the day, the activist-turned-politician said he considers Mr Hazare as his "Guru" and talks to him everyday.
"If he asks me to stop using the IAC's name, I won't use it," Mr Kejriwal said when asked about Mr Hazare and his associates' claim that the name remains with them.
Meanwhile, activist Kiran Bedi told reporters that the name IAC will remain with Mr Hazare.
"We will seek donations in the name of IAC. People can donate in the name of IAC. Arvind's organisation is PCRF (Public Cause Research Foundation)," she said.
After the first meeting of Mr Hazare's new team on Saturday, the group had insisted that they would retain IAC with Ms Bedi saying that it was not Mr Hazare who left the organisation but Arvind Kejriwal-led group which wanted to enter politics.
"They will be announcing the new name of the party. So, it won't be a problem on the name," she said. A press statement issued by the group yesterday said that Mr Hazare reconstituted the Coordination Committee to re-energise India Against Corruption movement, signalling that they were not ready to forgo the name.
Speaking to media, Mr Hazare said the group's bank account will be in the name of Ms Bedi, Sunita Godara and Lt Colonel Brijender Kokhar, all members of the new Coordination Committee.
