Punjab minister Sukhjinder Singh Randhawa is likely to be announced as the next Chief Minister, a day after his Congress colleague Captain Amarinder Singh resigned from the top post.
Mr Randhawa, 62, is the Jails and Cooperation Minister.
A resident of Gurdaspur district in Majha region, he is a three-time MLA - he won the assembly election in 2002, 2007 and 2017.
He has been the vice president of the Punjab Congress unit and the party's general secretary.
Mr Randhawa belongs to a family of Congress leaders. His father, Santokh Singh, was twice state Congress chief and a well-known leader in Majha region.
"Captain is our senior. I have always treated him like my father and he has treated me like his son," Mr Randhawa told news agency ANI today.
