Despite his successful career in law, Arun Jaitley's heart was always in politics. He knew that he was born to be in the battleground of politics.
He was the spokesman of the BJP before 1999 Lok Sabha Elections. In the Vajpayee government, Arun Jaitley was appointed as the Minister of State State for Information and Broadcasting (Independent Charge).
He took over the additional charge of the Ministry of Law, Justice and Company Affairs on 23 July 2000 following the resignation of Ram Jethmalani as the Union Cabinet Minister of Law, Justice and Company Affairs.
