In a statement here, Tharoor said: "Needless to say I am anxious to see that this case is investigated thoroughly, and (I) assure the police my full cooperation.

"Although we never thought of any foul play in the death of my wife, we all want that a comprehensive investigation be conducted and the unvarnished truth should come out," he said.

He added that he and all members of Pushkar's family wanted access to all the information on the basis of which Delhi Police had concluded that she was poisoned to death.

"We have not been provided copies of the post-mortem report and other reports of the inquiry like the CFSL report till date. We repeat our request for a copy of these reports to be provided to us immediately," said Tharoor.

Pushkar was found dead in mysterious circumstances in a luxury hotel in New Delhi in January last year. Delhi Police chief B.S. Bassi said Tuesday that she was poisoned to death.
