As the video above shows, the cameraman falls to the floor in the press scrum as the Labour leader gets off his battle bus. At first glance it appears as if he is dragged down. "It is categorically untrue to suggest that a Labour staff member in any way pulled over a BBC camera," the party insisted following allegations of foul play.
And Richard Perry, the cameraman, said he simply "got tangled up with someone's legs" and fell. "She was trying to guide me," he said of the press officer. "I fell over. Not her fault."
