Warning from union comes as corporation cuts local specialist correspondent roles as part of plan to save £500m

The BBC has been warned it risks entering a “doom spiral” of endless cuts and weaker public support for its services, as insiders anticipate the imminent closure of some TV and radio services.

Morale at the corporation is said to be extremely low as a series of cuts are slowly revealed to staff. In the latest announcement, the BBC said it would be reducing the number of local specialist correspondent roles.
