In 1960, Nkrumah promulgated a new constitution in which Ghana became a republic that could be easily governed, as the president was given the power to issue decrees without the approval of parliament, reject a large number of parliamentary decisions, and dismiss practically any government official without prior procedure. Control of the media was also granted to the regime.
He subordinated other institutions to his political party (CPP), so that in practice the party had a strong influence on organizations as varied as the Workers' Brigade or the Women's Council of Ghana.
Thus, having full control of the government, Nkrumah built a large number of valuable public works: many hospitals, schools and roads, and especially a large hydroelectric complex on the Volta River. His enthusiasm when building infrastructures, however, attracted foreign entrepreneurs who discovered that an ambitious idea and a bribe could earn them huge government concessions. For example, enormous and expensive silos for cocoa were built, to discover later that they were unusable.
