Before joining politics, Kejriwal had worked in the Indian Revenue Service as a Joint Commissioner of Income Tax in New Delhi. Kejriwal is a graduate in Mechanical engineering from Indian Institute of Technology (IIT) Kharagpur. In 2012, he launched the Aam Aadmi Party, which won in the 2013 Delhi Legislative Assembly election. Following the election, he took office as the Chief Minister of Delhi on 28 December 2013. He resigned 49 days later, on 14 February 2014, stating he did so because of his minority government's inability to pass his proposed anti-corruption legislation due to a lack of support from other political parties. On 14 February 2015, he was sworn in as Chief Minister for a second term after his party's victory in the Delhi Legislative Assembly election.
