The dolls of the Prince and the Prime Minister were created by UK firm and given to the pair during a trip to New York.

The pair were handed the gifts as they helped to showcase British innovation and technology in New York.
A new version of London's red Routemaster bus carried the pair to Manhattan's trendy Meat Packing district for an event highlighting creative UK firms blazing a trail in the US.
The event is part of the Great campaign, a Government initiative which promotes the UK around the world as a place to visit, study and do business in, on the back of the success of the Diamond Jubilee and London 2012.
