Under-Secretary-General of the United Nations

The majority of USGs are appointed by the General Assembly on the recommendation of the secretary-general for a fixed term of four years. Others (normally special envoys, Secretariat-appointees and non-programme management positions) are appointed directly by the UN secretary-general on their own authority. However, all USGs report to the General Assembly through the secretary-general. The only exception to this is the under-secretary-general for internal oversight services, who reports directly to the General Assembly. The distinction in method of appointment is important as USGs appointed by the General Assembly have a mandate independent of the secretary-general, and therefore is unable to remove them from office without the General Assembly's consent. This restriction has been seen by many commentators to weaken the secretary-general's ability to provide strong leadership and management within the United Nations System. ==Equivalent rank==

Some senior posts within the UN System have the equivalent rank of under-secretary-general but are either not entitled or choose not to use the formal title. The most prominent example of this is the administrator of the United Nations Development Programme, who is often referred to as the third most senior official within the UN System yet does not use the title of under-secretary-general. The UN high commissioner for human rights also has the rank of under-secretary-general, yet does not use the title. ==Diplomatic rank==

USGs have diplomatic rank equivalent to that of a national cabinet minister. Under Article 105 of the United Nations Charter they have diplomatic immunity. ==Senior Management Group (SMG)==

With over 50 people with the rank of under-secretary-general, unsurprisingly the influence and power they wield within the UN System varies dramatically. The most important USGs, controlling budgets, programmes or key activities, are also members of the United Nations Senior Management Group, whose objective is to ensure strategic coherence and direction in the work of the organization. The cabinet was approved by the General Assembly in 1997 as part of the reform proposal submitted by Secretary-General Kofi Annan. ==List of under-secretaries-general==
