Cilla Black and Paul O'Grady are to star in Led Astray, the pilot episode of a new BBC sitcom from Birds of a Feather creators Laurence Marks and Maurice Gran.

In the pilot episode Black plays Tanya, a woman who discovers her long-lost half-brother Arthur (O'Grady) is in prison and then takes him in upon his release.

Real-life friends Black and O'Grady will film the pilot later this month.

If a full series of Led Astray is ordered, it will be screened on BBC One.
