Secretary-General Kofi Annan called on the United Nations on Sunday to expand the Security Council from 15 to 24 members and scrap the Commission on Human Rights as part of a package of sweeping reforms at the world body. Annan said the council's expansion was crucial to making the United Nations "more broadly representative of the international community as a whole and the geopolitical realities of today."The secretary general urged member states to agree to green light his proposal prior to a summit of world leaders, scheduled for September 2005 at the United Nations in New York. Annan, in a report to be delivered today (Monday) to the 191-nation UN General Assembly, also waded into the debate over the March 2003 US-led invasion of Iraq, calling on the Security Council to set out rules for when it should authorise the use of military force. However, in the use of force as well as in reform of the Security Council, Annan did not set out his own recommendations, leaving these questions to UN members. Annan's plan aims to preserve the United Nations as the focus of global multilateral action and also to respond to growing criticism of the United Nations, fuelled by allegations of sex abuses by peacekeepers and mismanagement of the $67-billion oil-for-food plan for Iraq.
