A series of 12 Olympic and Paralympic posters, designed by leading UK artists including Tracey Emin and Chris Ofili, has been unveiled in London.

The images will be displayed in a free exhibition at Tate Britain next year, held as part of the London 2012 cultural festival.

Artist Tracey Emin said her poster for the Paralympics was based on the idea of a "cultural love letter".
