In the sixth edition of her new series celebrating portraits and portraiture through the eyes of ten Great Britons, Martha Kearney's guest is the editor-in-chief of British Vogue, Edward Enninful. His choice is a photograph of super-model Naomi Campbell taken in 1987 when she was just 17.

After three years of closure for major refurbishment and expansion the National Portrait Gallery, just off London's Trafalgar Square is set for re-opening. To mark the occasion the gallery, along with BBC Radio 4 have launched a celebration of great Briton's, with Martha Kearney hosting a Close Encounter between the likes of Sir Tim Berners-Lee, Dame Katherine Grainger and Edward Enninful and a portrait they choose to champion. For Sir Tim Berners-Lee it's the Suffragette campaigner Christabel Pankhurst, for Dame Katherine Grainger it's the first English woman to swim the channel, the largely forgotten Mercedes Gleitze.

In each episode we find out about the subject of the portrait, the moment at which their image was captured for posterity and the importance of image and identity for those who find themselves in the eye of the nation's attention today.
