Selected from 2,557 entries by artists from 80 countries around the world, the BP Portrait Award 2016 represents the very best in contemporary portrait painting.
From parents to poseurs, figurative nudes to famous faces and expressive sketches to piercing photo-realism, the variety and vitality in the exhibition continues to make it an unmissable highlight of the annual art calendar.
Now in its thirty-seventh year at the National Portrait Gallery, and twenty-seventh year of sponsorship by BP, the first prize of £30,000 makes the Award the most prestigious international portrait painting competition of its kind and has launched the careers of many renowned artists.
Moxon's portrait is of Harriet Harman, MP for Camberwell and Peckham whom Moxon approached to sit for a portrait after meeting her in 2013. The sittings took place in her office in Westminster, the addition of the Camberwell Beauty butterfly is a reference to her constituency. Moxon's technique uses layers of translucent glazes and is influenced by seventeenth-century northern European painting.
