Bharatiya Janata Party (BJP) leader Varun Gandhi filed his nomination in Sultanpur on Tuesday.
"My religion is only to serve the nation and keep our nation's flag high," Varun Gandhi said after filing his nomination.
Earlier, Varun Gandhi was accompanied by a huge procession to the district collectorate office to file his nomination.
Varun, who had earlier represented Pilibhit constituency in 2009, will now contest from Sultanpur. His poll opponents are Sultanpur MP Sanjay Singh's wife Amita Singh of the Congress, Shakeel Ahmed of the Samajwadi Party (SP) and Pawan Pandey of the Bahujan Samaj Party (BSP).
