Night Waves - Constable's Portraits

Artist Maggi Hambling discusses John Constable's portraits, the focus of a new exhibition at the National Portrait Gallery in London. Celebrated for his landscape paintings such as The Hay Wain, Constable's work as a portrait painter is far less well-known and, in fact, he produced more than 100 during his career. Hambling - now best-known for her controversial scallop sculpture dedicated to Benjamin Britten in Aldeburgh, and her memorial to Oscar Wilde in central London - talks about this less-explored part of Constable's work and discusses her own portraits - particularly of the jazz musician George Melly.
