"We take as genuine the Congress president's reply to Anna Hazare's letter. But she should take action if Digvijay Singh speaks just the opposite to what she said in her reply," Agnivesh told mediapersons in Ranchi.

"But if she does not rein in Digvijay Singh's statements, it will look like 'run with the hare and hunt with the hound'. This will spoil the image of the party and will be a big loss to it," Agnivesh said.

Singh had been frequently making remarks against civil society representatives led by Hazare, who is leading a campaign for a tough anti-graft law, and questioned their credentials.

Singh had also disapproved of Hazare's threat to go on protest if Parliament does not pass the Lokpal Bill by August 15 and his praise for Gujarat Chief Minister Narendra Modi saying that the veteran Gandhian should be careful of what he was speaking.

Agnivesh on Thursday visited the demolition sites in Ranchi following the anti-encroachment drive taken up by the district administration in the wake of high court's order to implement its earlier orders passed in 2003 and 2006 against encroachment.
