Jonathan Dimbleby (born 31 July 1944) is a British presenter of current affairs and political radio and television programmes, author and historian.

In 1972 he joined ITV's flagship current affairs programme This Week and over the following six years reported on crises in many parts of the world.

His report, for which he won the SFTA Richard Dimbleby Award, was used by the incoming regime to justify the overthrow of the Ethiopian Emperor Haile Selassie.

In 1979 he joined Yorkshire Television, where he wrote and presented three ITV network series: Jonathan Dimbleby In Search of the American Dream (1976), The Bomb (1979), The Eagle and The Bear (1980) and The Cold War Game (1981).

He wrote, presented and co-produced two documentary series: The Last Governor (BBC1 1997) about the final five years of British rule in Hong Kong, and Charles: The Private Man, the Public Role (ITV 1994), in which (the then) Prince Charles spoke about his first marriage and his relationship with Camilla Parker Bowles,[5] now his wife and Queen of the United Kingdom and Commonwealth Realms.

In 2022, following the death of Queen Elizabeth II, Dimbleby wrote and presented the documentary Charles, the Monarch and the Man, which aired on ITV on 13 September 2022.

He is a past president of Voluntary Service Overseas (VSO), of the Campaign to Protect Rural England (CPRE), of the Soil Association and of the RSPB.

His elder brother David Dimbleby is also a commentator on current affairs and presenter of BBC programmes.

In May 2003, Dimbleby began a relationship with the soprano Susan Chilcott, with whom he lived until her death from breast cancer in September 2003.
