Sunanda underwent medical check up at KIMS earlier this week

Thiruvananthapuram, Jan 18:

, who was found dead in a Delhi hotel last night, had undergone a series of medical tests at a super-speciality hospital here earlier this week.

Authorities at Kerala Institute of Medical Sciences Hospital (KIMS) here said the doctors, however, did not take any immediate decision on the course of treatment or medicines to be given.

Instead, they then decided to wait till all results are obtained and then meet again and decide on the future course. Sunanda, who was upset over an alleged extra-marital affair between her minister husband Shashi Tharoor and a Pakistani journalist, was found dead in a five-star hotel room last night.

Sunanda was upset over an alleged extra-marital affair of her husband

Sunanda had undergone a detailed medical examination at the hospital where she spent two days on January 13 and 14. Tharoor was also with her and the couple appeared "jovial", sources said.

Their plan was to return a few days later and decide on the treatment, based on results of the tests, the sources said. However, the hospital sources declined to divulge specific details of the tests.They said the medical board would hand over the results to police, if required.

A meeting of the doctors is underway in the hospital to look into the results. "A meeting of the medical board is on to consider the results of the test. We cannot say anything now on the matter," a hospital spokesperson said.

Meanwhile, a spokesperson of Tharoor said here that Sunanda's cremation was likely to take place in Delhi. However, a final decision would be taken after the post-mortem. Sunanda's son Shiv is already in Delhi.

Tharoor's sons Ishaan and Kanishk are expected to reach Delhi. The minister's sister Smitha has also left for Delhi from London.

Pushkar and Tharoor were at the centre of a raging controversy when reports emerged that she was upset over reported text and tweet messages between her husband and Mehr Tarar, Pakistani journalist.

The news of the death of Sunanda came as a shock to people in Thiruvananthapuram, from where Tharoor contested and won easily in his electoral debut in 2009 Lok Sabha polls.

Congress in the state is yet to react to the development as most of its leaders like Home Minister and KPCC president Ramesh Chennithala are yet to return to the state from Delhi in connection with the AICC meeting.

Leaders from the opposition parties have so far chosen to react in a subdued manner. Police had stepped up protection to Tharoor's constituency office in the heart of the city as soon as the news of his wife's death in a Delhi hotel spread.

The Tharoor couple, married in August 2010, were seen together at the famous Sree Padmanabhaswamy temple during the 'Lakshadweepam' festival on January 14.
