New Delhi: Bharatiya Janata Party MP Subramanian Swamy has time and again hogged the headlines for giving sleepless nights to the Gandhi family, J Jayalalithaa and many other bigwigs.
Most recently, Swamy launched a new tirade against RBI Governor Raghuram Rajan and Chief Economic Advisor (CEA) Arvind Subramanian, ruffling feathers in the government and the party.
Here are some of the interesting incidents linked to his life and career, which you would like to know:
Swamy's father was a renowned mathematician. Following his father's footsteps, the Rajya Sabha MP passed with a graduation degree in Mathematics from Delhi University's Hindu college.
The firebrand BJP leader received a PhD degree from the prestigious Harvard University at the meagre age of 24. Later at 27, he started teaching maths at the same institute.
In 1968, Swamy was invited by Nobel laureate Amartya Sen to join Delhi School of Economics, which he attended in 1969.
According to a report published in 'BBC', former prime minister Indira Gandhi got upset with Swamy over liberal economic policies put forward by him. In 1972, he was expelled from Indian Institute of Technology.
His sacking from IIT, however became the turning point in political career. Swamy, who was by then known as a daring figure, knocked on the doors of the judiciary and finally won the case in 1991.
After winning the case, the county's well-known lawyer attended IIT for one day and resigned thereafter.
Late Nanaji Deshmukh sent Swamy to Rajya Sabha on a Jan Sangh ticket in 1974.
The BJP leader served as a finance and law minister during Chandra Shekhar Singh government. Notably, despite being in the opposition, he was given a Cabinet rank by late PM Narasimha Rao in his government.
Swamy was very close to late PM Rajiv Gandhi and during Bofors scam, he told the Parliament that the former didn't get any money as kick-backs for the defence deal, the BBC report said.
The BJP leader was instrumental in leading the 2G spectrum scam to the Supreme Court.
At present, he is fighting the National Herald case in which Congress president Sonia Gandhi and party vice president Rahul Gandhi along with some senior leaders of the grand old party are named as accused.
