Lynda Baron returning to Doctor Who

It has been reported by The Wales on Sunday that Lynda Baron will be returning to the show, during a summary of cast seen filming last week alongside James Corden in the episode currently being shot by Steve Hughes:

Lynda Baron appeared in the Fifth Doctor story Enlightenment (1983) playing Captain Wrack, and also sang "The Ballad of the Last Chance Saloon" that featured throughout the First Doctor story The Gunfighters (1966). Outside of Doctor Who she is probably best remembered as nurse Gladys Emmanuel in the Ronnie Barker sitcom Open All Hours.

No official confirmation of Baron's casting has been made at present.
