Does anybody know the actor or actress who has appeared in the most episodes of Emmerdale? I don't trust IMDB because it says Chas has appeared in over 1000 episodes since her debut in 2003 but Alan has only appeared in 511 episodes, this information cannot be correct? It says Shelia Mercier has only appeared in 220 episodes? This information deffo cannot be correct. Neither can it be correct that Chas has appeared in the most episodes in the shows history. Can anybody help?
