Joining the BJP, Varun represents the young face and third generation of the party. Representing the Pilibhit constituency he became the youngest General Secretary in the history of BJP.
In the 2009 elections, Varun was made the face of BJP in Pilibhit constituency in place of his mother Maneka. He won by a large margin. This victory was remarkable as it had left behind the other Gandhi family members i.e his mother Maneka, Sonia and Rahul.
