German security services have identified dozens of public servants, including in the police and army, as belonging to a far-right movement that denies the existence of the very republic they serve, the weekly Der Spiegel magazine said.

A report drawn up by the security services estimates there is a "high double-digit number" of public servants who belong to the "Reichsbuerger," or Citizens of the Reich, a mystical nationalist movement which maintains that the Reich continued after Germany's defeat in World War II, Spiegel reported.

Investigations are under way against 11 members of Bavaria's state police, five of whom have been suspended from duty. There have also been 11 cases in Germany's Federal Police and four of them have had their service weapons confiscated, Spiegel said.
