Besides Arvind Kejriwal, his family and Raghav Chaddha, no one outside the family has been invited.
Punjab Chief Minister Bhagwant Mann today married Gurpreet Kaur, a 32-year-old doctor, in a simple, private ceremony at his home in Chandigarh.
Bhagwant Mann and Gurpreet Kaur, dressed in red and gold, were seen at their "Anand Karaj" ceremony in visuals on TV and social media.
Delhi Chief Minister Arvind Kejriwal and Aam Aadmi Party (AAP) MP Raghav Chaddha were among the few guests at the low-key wedding that mostly featured family and relatives.
Raghav Chaddha shared many photos of the wedding, calling Bhagwant Mann his older brother.
"Mann sahab nu lakh lakh vadhaiyan (many congratulations of Mann Sahab)," Mr Chaddha tweeted, sharing a photo in which he and Arvind Kejriwal were seen walking with the groom.
Bhagwant Mann, 48, has known Gurpreet Kaur for a few years through family ties. Gurpreet Kaur reportedly also helped him during his Punjab election campaign.
"Today is a day of immense happiness that my younger brother and Punjab Chief Minister Bhagwant Mann ji is getting married and is making a new beginning," Arvind Kejriwal told reporters at the airport.
"His mother's dream was for him to marry again and settle down. I congratulate him. God bless the couple," said Raghav Chaddha, who helped plan the wedding.
Mr Mann, a former stand-up comic, was divorced six years ago and has two children from his previous marriage. His children live with their mother in the US. They came for Mr Mann's oath ceremony on March 16.
The wedding menu was a blend of Indian and Italian cuisine; it included Karahi Paneer, Tandoori Kulche, Dal Makhani, Navratan Biryani, Mausami Subzian, Apricot Stuffed Kofta, Lasagna Siciliano and Burrani Raita. A fresh fruit trifle, moong dal halwa, shahi tukda, angoori rasmalai and dry fruit rabri were also part of the elaborate spread.
The bride, Gurpreet Kaur, completed her MBBS from a private university in Haryana four years ago.
She shared a photo on Twitter this morning and wrote, "Din Shagna Da Chadya (the day of my wedding has arrived)".
Dr Kaur's neighbours in Pehowa in Kurukshetra said they found out through the media that she was marrying the Chief Minister.
"We know the bride by the name of Gopi. It was only in the morning that we came to know she was getting married to the Punjab Chief Minister," said a neighbour quoted by ANI.
Gurpreet Kaur is the youngest of three sisters.
