Sorry, it is not Mark Burdis. He looks slightly similar, but Mark is younger. He was also the milkman in the milk adverts, who had the dancing milk bottles along the path, and then cries "empties" and all the empty milk bottles jump up into the milk carrier.
his name is Mark Flitton he was my drama teacher at school and has been in eastenders, the bill, spooks, the grid and has his own theatre group in swindon
