From Town Councils past the State Parliament to the Bundestag (National Parliament)
The people's party CDU contributes to the political development of principles in our country on various parliamentary levels.  In order to fulfill that purpose and work together more efficiently, delegates come together to form parliamentary groups.  The organization of the parliamentary work orientates itself according to the strength of each individual parliamentary group.  The more members that a parliamentary group has, the greater its amount of representatives that are sent to specific committees, for instance.
