Around 20 invitees — including officers from the army, navy and air force, and consular representatives and judges — have been invited to the Independence Day programme on Red Road.

The event, to last a little over 30 minutes, will be an abridged affair in keeping with Covid protocols, officials at Nabanna said on Friday. There will be no seating arrangements for anyone apart from the guests.

Chief minister Mamata Banerjee is scheduled to arrive at the venue at 10.30am, sources in Calcutta police said.

“Red Road-bound traffic will be diverted for over an hour on Sunday till the function is over,” said a senior police officer at Lalbazar. “Police officers in close proximity to the chief minister will have to carry an e-certificate of their double dose vaccination.”

Tableaus depicting some of the initiatives of the Bengal government such as Khela Hobe Divas, students' credit card and Duare Sarkar will be on display. There will also be tableaus on Subhas Chandra Bose and unity in diversity.
