"I may file a PIL in court seeking a thorough probe into the matter relating to the death of Sunanda Pushkar," Swamy said while replying a question here on the sidelines of a programme. Swamy said he had sought court's interference on many occasions during the UPA regime but "have not moved court on any matter after the NDA came to power".
"However, I may file a PIL in the case of Sunanda Pushkar's death even as her husband has been making rounds to the BJP office in Delhi," he said.
Swamy has for long demanded a special investigation of Pushkar's death alleging foul play. Sunanda was found dead in a five-star hotel in south Delhi on the night of January 17, after her Twitter spat with Pakistani journalist Mehr Tarar over an alleged affair with her husband.
A team of AIIMS doctors had last month submitted a fresh report to police on Sunanda's death after examining her viscera and maintained that she died of poisoning.
