Veteran Dad's Army actor Bill Pertwee has blasted the quality of writing on modern day sitcoms.

80-year-old Pertwee, who played Hodges in the much-loved show, told the Daily Mail that today's comedy writers "try to make their point by being too aggressive. If they can't fit a joke in a line they put a four-letter word there."

Speaking at the launch of his autobiography, he added: "I just wonder why they don't concentrate more on characters and situations. Steptoe and Son, Dad's Army and Till Death Do Us Part had marvellous situations, the jokes got there themselves."
