He is comforted by a woman, who strokes his head while Mr Fellows remains on the ground.
Mr Fellows eventually stands up and stares at Mr Amesbury, who then leaves in a cab.
Mr Amesbury, who was suspended from the Labour Party by Sir Keir Starmer over the incident, is facing pressure to stand down from his Runcorn and Helsby seat.
Mr Fellows was punched while waiting for a taxi in Frodsham, Cheshire.
According to The Times, the two men rowed about the upcoming 33-day closure of the Sutton Weaver swing bridge.
Mr Amesbury had recently described the closure as “unacceptableâ€. A witness said the row also touched on winter fuel payments being scrapped.
We can reveal that Mr Fellows, who lives in Frodsham, was caught drink-driving in the town in June.
He was banned from driving for two-and-a-half years after he was found to be almost double the legal limit.
