Sunanda's death came a day after Tharoor issued what he called a joint statement from the couple last year, saying they were “happily married and intend to remain that way”.

The court petition, which was filed by Bharatiya Janata Party's (BJP) Thiruvananthapuram district secretary S Suresh, had sought to declare Tharoor's victory and invalid and proclaim BJP candidate O Rajagopal as a winner.

The petition alleged that Tharoor failed to disclose his wife's assets as required by the law, during his candidature. Tharoor told the court that his wife did not have assets in India and they were not transferred to him. He further asserted that he does not plan to lay a claim for Sunanda's assets.

After an autopsy initially concluded Sunanda probably died of an overdose of anti-depressant drugs, Indian police said in January this year that she was poisoned and a case was registered.

Tharoor said he was “stunned” to hear his wife's death was being investigated as murder, adding that he had never suspected foul play. Tharoor may be questioned by Delhi police after they opened a murder investigation against “unknown persons”.
