To mark the 90th anniversary of the BBC World Service, we trace the development of the Caribbean Service.

Its beginnings go back to the early 1940s when the BBC’s first black producer, Una Marson was employed.

She created Caribbean Voices, which gave future Nobel laureates such as Derek Walcott their first international platform.

In 1969, one of the UK’s best known newsreaders, Sir Trevor McDonald, left Trinidad to join the BBC Caribbean Service as a producer.

He reflects on its legacy. Produced and presented by Josephine McDermott.
