Sonia Gandhi filed her nomination in the presence of Congress President Rahul Gandhi, party General Secretary Priyanka Gandhi, son-in-law Robert Vadra and grandchildren Rehan and Mariya after holding a roadshow.

Asked if she feels that Modi is invincible, Sonia Gandhi said: "Not at all. Don't forget 2004. Vajpayeeji was (considered) invincible, but we won."

Rahul Gandhi added: "There have been many people in Indian history who had arrogance to believe that they're invincible and are bigger than the people of India.

"Modi in the last five years has done nothing for the people. His invincibility will be in full view after election results."

The UPA Chairperson has represented the Rae Bareli seat undefeated since 2004. Before Rae Bareli, she represented Amethi in the Lok Sabha from 1999-2004.

In the 2014 Lok Sabha elections, the Congress managed to win only in Amethi and Rae Bareli out of the total 80 seats in Uttar Pradesh.

Elections in Rae Bareli are scheduled in the fifth phase on May 6. Counting of votes will take place on May 23.
