The Farrukhabad administration had denied permission to the IAC to hold demonstration to make fresh expose against alleged irregularities by Zakir Husain Memorial Trust of Law Minister Salman Khurshid, IAC sources said.
IAC convenor Laxman Singh along with his associates started the dharna in front of the magistrate's office.
The city magistrate later granted permission to the IAC activists to hold the November 1 programme, they said.
IAC member Sanjay Singh, meanwhile, told reporters in Lucknow that Kejriwal's programme would be held in the home district of Khurshid at all cost even if they have to land in jail.
Singh said IAC has written a letter to Chief Minister Akhilesh Yadav requesting to give permission for Kejriwal's programme in Farrukhabad.
