The first official painting of the Duchess of Cambridge has been unveiled.
It was painted by the artist Paul Emsley and took several months using a technique of building thin layers of oil and glazes on canvas.
The duchess sat for the artist twice. Mr Emsley also worked from a series of photographs he took of Catherine.
The portrait is on show at London's National Portrait Gallery, of which the duchess is patron.
Nicholas Witchell reports.
