Prince Charles says he's "enormously proud" to be the Patron of the National Police Memorial Day.
Speaking ahead of the event in Cardiff, the Prince of Wales spoke of how "our courageous policemen and women routinely endure hazardous environments."
He will be honouring the memory of PC Steve Rawson, who died in Southampton earlier this year.
The 40 year old Police officer leaves behind a wife and 2 young children.
