President Olusegun Obasanjo has expressed support for the proposal by the African Union (AU) to increase the membership of the United Nations (UN's) Security Council to 26. He stated this at the inaugural lecture for Course 14 of the National War College (NWC), noting that Africa has a vital role to play in the planned changes in the UN's Security Council, which is geared towards global peace. President Obasanjo, who was represented at the occasion by the Minister of State for Defence, Roland Oritsejafor, said the AU was in support of the proposal by the Group of Four, dubbed Model A, except that it will give the new members veto privileges.
