Since August 1982, the highest office of the republic has been the President of the Sahrawi Arab Democratic Republic, a post held by the secretary-general of the Polisario Front, presently Brahim Ghali, who appoints the Prime Minister, presently Mohamed Wali Akeik. The SADR's government structure consists of a Council of Ministers (a cabinet led by the Prime Minister), a judicial branch (with judges appointed by the President) and the parliamentary Sahrawi National Council (SNC; the present speaker is Kathri Aduh). Since its inception in 1976, the various constitutional revisions have transformed the republic from an ''ad hoc'' managerial structure into something approaching an actual governing apparatus. From the late 1980s the parliament began to take steps to institute a division of powers and to disentangle the republic's structures from those of the Polisario Front, although without clear effect to date.
