Punjab Chief Minister Bhagwant Mann on Friday moved a resolution in the state Assembly seeking immediate transfer of Chandigarh to Punjab.
In the past, the House has passed a number of resolutions urging the Central government to transfer Chandigarh to Punjab, he said.
"For maintaining harmony and taking the sentiments of people into account, this House once again recommends to the state government to raise the matter with Central government to immediately transfer Chandigarh to Punjab, according to the resolution moved by CM Mann in the House.

Chandigarh is the joint capital of Punjab and Haryana.
Earlier, after the session began, Congress MLA Rana Gurjeet Singh and his son Rana Inder Pratap Singh, who is an Independent legislator, were administered oath of office.
