Princess Anne arrives at Hearing Dogs for Deaf People's HQ

After a brief tour of The Grange, Princess Anne was shown a demonstration of a hearing dog in action.

One of the clever canines, named Brock, was given the important task of unveiling - on the Princess's command - a special commemorative stone.

The royal visit continues throughout the afternoon.

See the Bucks Free Press later for pictures from the event.
