The one-time guest star is among the signatories to a letter to the BBC's director general, Matt Brittin, warning that removing the recording of the rural soap opera from the Midlands would threaten the programme's future.
It emerged this week that the BBC plans to stop recording The Archers in Birmingham for the first time in the show's 75-year history. Staff were told last week that the corporation had abandoned plans to build a bespoke studio at the Tea Factory in Digbeth, its new Birmingham headquarters.
Production staff will still move to the Tea Factory, but the broadcaster is now looking for an existing studio where the show could be recorded. The West Midlands is included in the search, but there is no guarantee The Archers will be recorded in the region.
The letter, signed by more than 100 current and former cast members as well as editors, scriptwriters, sound effects workers, programme advisers and the unions Equity and WGGB, says: "The Archers leaving the Midlands is akin to Corrie leaving the north-west, or EastEnders the south-east. It is born of the very fabric of the place, and deserves to stay at home."
It adds: "Removing the recording of The Archers from the Midlands and divorcing the production team from the cast will have a tangible impact on the quality of the programme and represents an existential threat to its future."
