“The politics of Namibia takes place in a framework of a presidential representative democratic republic, whereby the President of Namibia is elected to a 5 year term and is both the head of state and the head of government, and of a pluriform multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the two chambers of parliament. The Judiciary is independent of the executive and the legislature”.

Also try doing a search on ‘namibian politics’. I found several sites that might be helpful to you. Good luck:)
