The National Unionist Party of Greater Germania (German: Nationalunionistische Partei der Großgermania, NUPG) is the largest and only legal in Großgermania. Although organization of opposition parties was deemed to be illegal under the Constitution of Großgermania by the Supreme Court, as ratified by the 2009 parliamentary election, opposition to the Party within the Reichstag is provided by independent members. The NUPG is led by Michael von Preußen, the Emperor of Großgermania, and is largely responsible for the content of the newspaper Imperial Observer.
