In a statement to investigators after wife Sunanda Pushkar's death, Congress MP Shashi Tharoor had said that the couple had "some misunderstanding" which was cleared.
NDTV has accessed Mr Tharoor's statement last year to the Sub Divisional Magistrate, who was inquiring into Ms Pushkar's death as the couple had been married less than seven years.
"Our married life was very happy and some misunderstanding which was there was cleared and she was happy about it," Mr Tharoor stated.
He also revealed that his wife was "a very happy personality" but was very ill after two surgeries. She was dependent on Alprax tablets to sleep, he said.
Days before her death, Ms Pushkar, 52, had been admitted to a hospital in Kerala for suspected lupus.
Mr Tharoor said she was discharged on January 14 (2014), after which they came to Delhi.
Ms Pushkar was found dead on January 17 in the five-star hotel suite in Delhi the couple had checked into, days after she had a public showdown on social media with a Pakistani journalist she had alleged was having an affair with her husband.
Earlier this month, the police registered a murder case against unknown persons, saying that Ms Pushkar died of poisoning - either given orally or injected.
In his statement to the magistrate, Mr Tharoor said he went to Jaipur that day, and came back to the hotel at 8 pm.
"I decided to wake up Sunanda at 8.30 pm. I entered the bedroom of the suite asking 'darling how are you feeling,' there was no reply," the MP said.
"I placed my hand on her forehead to check for fever and found it very cold. Her hands were stiff. I immediately called the doctors and the hotel management. But it was already too late," he stated.
The Congress leader could be questioned in the next few days, Delhi Police Chief BS Bassi told NDTV today.
The police have already questioned several aides and friends of the couple.
