The wife of Indian minister Shashi Tharoor, found dead in a Delhi hotel room on Friday, died a "sudden and unnatural death", an autopsy has found.
Tharoor, who was earlier admitted to hospital with chest pains, took his wife's body away for cremation.
The couple caused a media stir on Twitter on Wednesday with a series of messages appearing to reveal he was having an affair with a journalist.
They later insisted they were happily married, blaming "unauthorised tweets".
The full results of the post-mortem examination are due to be released in the next two days.
Tharoor's aide, Abhinav Kumar, had earlier told reporters that she had appeared to be asleep.
Tharoor, a former UN diplomat, was forced to resign from his first ministerial position in 2010 amid controversy over his involvement in bidding for a cricket team.
Pushkar had allegedly received a free stake in the Indian Premier League franchise he was bidding for.
He was appointed minister of state for human resource development in 2012.
