He Guards Another Coronation Stone - A police constable here needs watch over the Saxon Coronation Stone (in foreground) at Kingston-on-Thames (near London). The policeman was put on guard after the scone coronation stone was stolen from Westminster Abbey on Christmas Day. Scottish nationalists threatened last March to remove the Saxon Coronation Stone and hold it as ransom against the return of the Abbey Stone, which, police believe, they have now stolen.
