There is only one political party recognized by law in a dominant one-party system.
One party system may be defined as a political system in which only one political party is legally and constitutionally allowed to operate. Every body in the state who wishes to participate actively in politics must have to coin the only party in existence. Example are:
1. China
2. Spain
3. Tanzania
4. Ghana (during the time of Kwame Nkrumah)
5. Zambia
6. Guinea (under Ahmed Toure)
These countries have at one time or the order operated this system.
