Gordon Brown Calls for World Government

Gordon Brown has many times announced the need for a World Constitution. Others are calling for enforcement of international law.

On September 13, 2012, in his first report to the UN Human Rights Council in Geneva, Switzerland, Alfred de Zayas, the UN Special Rapporteur on the promotion of a democratic and equitable international order, urged world governments to respect the UN Charter as the World Constitution and to work to achieve an equitable and democratic international order in which law is applied uniformly among countries.
