An anti-nuclear protester who kept popping up in interviews behind former spin doctor Damian McBride was tackled to the ground by blogger Iain Dale after refusing to move.
Dale, who is also McBride's publisher, says he intervened in order to protect the author.
The scuffle happened on Brighton seafront this morning on the fringes of the Labour party conference.
