In February 2006, after resigning from the post of Joint Commissioner in the Income Tax Department, he became a full-time activist and started an NGO, Public Cause Research Foundation, with his award money as the corpus fund.
The 45-year-old came into limelight from the Jan Lokpal agitation led by his one time mentor Anna Hazare in 2011.
He was part of Team Anna, along with first woman IPS officer Kiran Bedi, Prashant Bhushan and others.
While they were feeling "betrayed" by the government when it rejected their draft, the Congress and leaders of other political parties challenged them to join politics, win elections and come to Parliament if they wanted to "fight the system from within", root out corruption and get the Jan Lokpal Bill passed.
The indefatigable activist decided to take a plunge into politics and formed "Aam Aadmi Party" on November 26 last year, after a formal split of Team Anna.
