"I would be happy if Pawar becomes the PM. He is my political guru. I entered politics because of him," Shinde said in an interaction with editors of a Marathi newspaper here.
"Everone has ambition. He has been trying since 1992," he said.
Shinde's remarks came ahead of Congress' crucial session on January 17, amid reports that party vice-president Rahul Gandhi could be named its Prime Ministerial candidate at the meet.
Pawar has been trying to become PM since 1992, but was a "victim of Delhi politics" he said.
Pawar, who broke away from Congress on the issue of Sonia Gandhi's foreign origin in 1999 to form NCP, has made it clear that he would not contest the 2014 Lok Sabha elections and instead intends to take the Rajya Sabha route to Parliament.
