New Delhi, Sep 22 Former Union Minister P. Chidambaram on Friday described as an "absolute lie" the CBI statement in the Supreme Court that his son Karti has many offshore accounts. "By quoting CBI as the soure, the lie does not become the truth," he said reacting to CBI's claim in the court during a hearing on the Look Out notice against Karti which he has challenged. "Why doesn't CBI take my open offer and name the alleged 'undisclosed assets'? I have already made a public statement that my family and I will execute any document necessary to transfer the alleged 'undisclosed asset' to the government so that government can become the owner," Chidambaram said. The Congress leader also demanded that media withdraw the story forthwith.
