The Congress MP and former Minister of State for HRD, who was the chief guest at the graduation day function of a college here, avoided answering any query by persistent mediapersons.
Earlier during his speech at the function at the DG Vaishnav College, he said students awaited hard roads as challenges ahead in their lives. "But you should believe in yourself, you should believe in the truth. I have been on those hard roads and that was the only way I was able to cope as well," he said.
Though the reporters attempted to elicit a response from him as he came out after the function, he didn't utter a word. Sunanda was found dead in a 5-star hotel in South Delhi on the night of January 17, a day after her Twitter spat with Pakistani journalist Mehr Tarar over an alleged affair with Tharoor.
The new report by the three-member panel of doctors, who had conducted the autopsy on her, maintained that she died of poisoning.
The report was prepared on the basis of the findings of the Central Forensic Science Laboratory (CFSL) which had examined Sunanda's viscera.
The viscera report of CFSL in March had hinted at drug poisoning but police considered it as inconclusive.
