"I will be very happy if she comes... I will indeed be grateful if she comes for a roadshow," Mistry, who is filing his nomination for the Lok Sabha polls on Saturday, said. (Agencies)
His remarks came close on the heels of reports quoting Gandhi family friend and key Congress strategist Sam Pitroda that Priyanka will share her brother and Congress Vice President Rahul Gandhi's burden.
She will interact with media more and also campaign aggressively in the coming days, Pitroda has said, making it clear that the 42-year-old would complement her elder brother's efforts, not overshadow them.
Mistry's remarks also came a day after all India Mahila Congress (AIMC) president Shobha Ojha said in Bhopal that it is the wish of all Congressmen that Priyanka should campaign for the party in the entire country.
The reports have come amid the talk that Priyanka, who has been helping the Congress war-room in strategising its election campaign, may be taking baby steps towards a more active political role.
Ahead of the filing of nominations, Mistry said that he was confident of a victory in Vadodara "because of the solid support of the party and people."
"I am full of confidence that I will turn the tables," Mistry, who is a known detractor of Modi, said.
Asked whether the party would be putting up a formidable candidate in Varanasi too against Modi, Mistry, who is in charge of party affairs in Uttar Pradesh, said "certainly".
"I am busy in campaigning in Vadodara," he said when asked as to who will be the Congress nominee in Varanasi and when his name will be announced.
Priyanka's possible involvement in active politics has to be seen in the context of senior Congressman Janardan Dwivedi's statement quoting late Rajiv Gandhi, saying how even as a teenager Priyanka was well inclined towards politics.
"I will be very happy if she comes... I will indeed be grateful if she comes for a roadshow," Mistry, who is filing his nomination for the Lok Sabha polls on Saturday, said.
