While filing nomination, Deol will be accompanied by Kavita Khanna, wife of former Gurdaspur MP late Vinod Khanna, and Union Minister Jitendra Singh, the BJP said.
Deol on Sunday met Prime Minister Narendra Modi. Modi appreciated Deol's "humility and deep sense of passion for a better India".
"Happy to have met him today. We are all rooting for his victory in Gurdaspur".
“We both agree - Hindustan zindabad tha, hai aur rahega,” the Prime Minister had tweeted along with a picture.
