The video footage shows an elderly man in sunglasses, believed to be Great Yarmouth councillor Tom Andrews, accusing the group of doing damage to UKIP campaign boards.

"Why are you coming here to intimidate us?" asks Braniff-Herbert in the video.

"I'm intimidating four guys?" replies Andrews. "Yeah, old-age pensioner. Oh, fuck off."

"Sorry, excuse me?" Braniff-Herbert says.

"I said fuck off," says Andrews, approaching Braniff-Herbert, who replies, "You said what?"

The video appears to show Andrew's right hand making contact with the left side of Braniff-Herbert's face.

"Now you're getting me angry now," said Andrews.

Braniff-Herbert told him to leave, adding, "You just physically assaulted me."

"No, I didn't," replied Andrews. After further exchanges in which Braniff-Herbert repeats the accusation, Andrews replies, "Oh, I don't give a shit," before leaving.
