Papua New Guinea is divided into four regions, which are not the primary administrative divisions but are quite significant in many aspects of government, commercial, sporting and other activities.
The politics of Papua New Guinea takes place in a framework of a parliamentary representative democratic multi-party system, whereby the Prime Minister is the head of government. Papua New Guinea is an independent Commonwealth realm, with a governor-general, nominated by the National Parliament, acting as head of state. Executive power is exercised by the government. Legislative power is vested in both the government and parliament.
The culture of Papua New Guinea is many-sided and complex. It is estimated that more than 7000 different cultural groups exist in Papua New Guinea, and most groups have their own language. Because of this diversity, in which they take pride, many different styles of cultural expression have emerged; each group has created its own expressive forms in art, dance, weaponry, costumes, singing, music, architecture and much more.
