"Thank you to the people of Chandigarh for supporting @BJP4India & @Akali_Dal_. This shows the importance people attach to good governance," he tweeted.
"Congratulations to BJP & Akali Dal Karyakartas for working with remarkable determination on the ground and serving people. @BJP4Chandigarh," Modi said.
Akali Dal and BJP got a shot in the arm ahead of Punjab assembly polls as the alliance defeated Congress in the Chandigarh municipal corporation elections in which demonetisation had emerged as a key issue.
Congress had majority in the Municipal Corporation after the previous three elections. However, in the mayoral election in January this year, the BJP candidate had won.
Today's result is the biggest ever victory for any single political party in the body since its inception in 1996.
