Left Congress and ISF announced that they will fight together in an alliance named as 'Sanyukta Morcha' from Brigade Rally on 28 February 2021.

After the final seat sharing agreement was concluded, it was announced that the Left Front will contest on 165 seats, Congress will contest on 92 seats and ISF will contest on 37 seats.
