The BBC has announced the closure of its Caribbean Service as part of an exercise to rationalise its operation.
The BBC says five of its 32 World Service language services will be closed.
Staff has been informed that up to 650 jobs will be lost from a workforce of 2,400 over the next three years.
In addition to the Caribbean Service, the Macedonian, Albanian and Serbian services will be axed, as well as Portuguese for Africa, in a bid to save 46 million pounds a year.
Audiences are estimated to fall by more than 30 million, from 180 million to 150 million a week.
Correspondents at the affected services have already been informed of the closures, expected to become effective in March.
The BBC Caribbean Service has been broadcasting since 1939.
