Ranga was deeply involved in student politics right from early in life, as one of the founding members and the first president of the National Students Union of India (NSUI). It was no less a person than Prime Minister Indira Gandhi, whose great personal favourite he was, who called him to take up this post after going through due process. By 1973, he had also been elected a member of the All India Congress Committee. In 1977, on obtaining a degree from
Kirori Mal College,
Delhi University, he moved to
Madras to practice in labour law. When the Congress was re-elected in 1980, Rangarajan was asked by his very dear friend, soon-to-be-Prime Minister
Rajiv Gandhi, to play an active role in politics. He contested and won the 1984 elections from
Salem Lok Sabha constituency.
P.V. Narasimha Rao appointed him Minister of State for Law, Justice and Company Affairs in July 1991. Despite his personal sense of loyalty to
Narasimha Rao, Ranga was unable to support him in what was increasingly being seen as a corrupt Congress regime. In a letter to the President he raised several issues with regards to corruption allegedly perpetrated by the Prime Minister, based on documents he had in his possession and that formed the basis of the
Vohra Committee report. In this letter he asked the President to ask the Prime Minister to step down and face an investigation against the charges. In late 1993, Rangarajan resigned as Cabinet Minister. In May 1995, Rangarajan resigned from the primary membership of the Indian National Congress and along with
Arjun Singh,
N.D. Tiwari,
Sheila Dikshit and others, founded the Congress(T). However, Rangarajan lost his seat in the 1996 Parliamentary elections during which his new party suffered a crushing defeat. In December 1997, Rangarajan joined the
Bharatiya Janata Party. He won from the
Tiruchirapalli Lok Sabha constituency in 1998 and 1999 and became one of the torch-bearers of the BJP in
Tamil Nadu. He served with distinction as the Union Minister for Power and Parliamentary Affairs, holding additional charge of Law, Justice and Company Affairs, and Mines, in the
Second Vajpayee Ministry from 1998 to 1999 and in the
Third Vajpayee Ministry from 1999 until his death in 2000. == Death ==
