David Liddiment joined Granada Television’s Promotions department in 1975 after a stint in the advertising industry where he had briefly worked after graduating from Liverpool University.

His real ambition however was to direct but after a number of unsuccessful applications to join the directors training scheme, he was advised to try for a Researchers board.

After a couple of unsuccessful attempts he finally became a researcher working initially on This is Your Right. Six months later David Boulton invited him to be a researcher on a new drama documentary unit being set up by himself and Leslie Woodhead.

He finally became a director, working not only on a wide range of local programmes but on both Albion Market and Coronation Street, before being appointed head of Light Entertainment and deputy controller to Steve Morrison.

In 1992 he was made director of programmes.

He left Granada to help set up his own independent production company and later became a trustee of the BBC.
