Video: Duchess attend first solo engagement at National Portrait Gallery The Duchess, who is using her husband's six-week tour of duty in the Falklands as a perfect opportunity to publicise the four charities of which she is Patron, was given a preview of an exhibition of the late Lucian Freud's work, which opens to the public today. The visit came as St James's Palace confirmed the Duchess has agreed to a request from the gallery to pose for a portrait. Wearing a double-breasted, 1950s-style dress by the high street clothing label Jesire, the Duchess was greeted by Freud's daughter Esther and Sir Paul McCartney's photographer daughter Mary, a trustee of the gallery in London's Trafalgar Square. Jeremy Hunt, the Culture Secretary, and Sandy Nairne, director of the gallery, also joined her on an hour-long tour of more than 100 paintings on show.
