LONDON -- The Royal Canadian Mounted Police have become Queen Elizabeth II's personal bodyguards  -- for a day, at least. 

In a nod to family history, Britain's queen invited the Mounties to take part in her Diamond Jubilee celebrations. Fifteen members of the police force, in their iconic red jackets, changed roles with the Royal Mounted Regiment on Wednesday. 

The Mounties also brought a few women with them to shake things up.
