Capturing the Queen: Her reign in pictures

A new portrait of the Queen and the Duke of Edinburgh has been unveiled to mark the Queen's forthcoming Diamond Jubilee and the Duke's 90th birthday.

It is part of a nationwide exhibition showing images spanning the six decades of the Queen's reign.

Our royal correspondent Nicholas Witchell went to have a look.
