Mr Tharoor, a prominent MP with the opposition Congress party and a former diplomat to the United Nations, married the businesswoman Sunanda Pushkar in 2010. She had taken to Twitter two days before to accuse a Pakistani journalist of stalking her husband.
The Delhi Police, in its affidavit filed in the apex court, had said that a draft final report has been sent to the prosecution department of the Government of National Capital Territory of Delhi for "legal scrutiny" and it would be filed in the concerned trial court after being vetted.
"No one who knew Sunanda believes she would ever have committed suicide, let alone abetment on my part", he posted on Twitter.
In a 3000-page chargesheet filed before metropolitan magistrate Dharmendra Singh, police alleged that Tharoor, who is the Lok Sabha MP from Thiruvananthapuram, subjected his wife to cruelty.
Indian Parliament member Shashi Tharoor was charged Monday with involvement in his wife's death four years ago, Delhi police announced. They were having regular fights, which she had confided in other persons too.
A police officer, who did not wish to be named, said that the analysis report, though not admissible as evidence in court, supports other evidence such as medical and autopsy reports, statements of those who knew the couple and the phone messages they have retrieved.
September 30: Viscera report submitted to Delhi Police.
February: Viscera samples sent to the Federal Bureau of Investigation lab in Washington.
November 10: Viscera report from the Federal Bureau of Investigation said radiation in Pushkar's viscera samples was within permissible levels and did not cause her death. The couple were staying in the hotel as their house was being renovated but on the day, when she did not wake from her sleep, Shashi Tharoor informed the Police. Though some people in the Congress felt that Tharoor was trying to build bridges with the BJP leadership with his book "Why I am a Hindu", his position may be weakened if he gets convicted.
October 26, 2017: The Delhi High Court dismissed Subramanian Swamy's plea.
Though it was a murder probe with the FIR registered under IPC Section 302 (murder), police have charged Tharoor under Sections 306 (abetment) and 498A (cruelty by husband) of the Indian Penal Code. Swamy, however, moved the Supreme Court in January this year.
