"The role of the United Nations is to lead. Each of us here today shares that heavy responsibility. It is why the UN matters in a different and deeper way than ever before. To lead, we must deliver results. Mere statistics will not do. We need results that people can see and touch - results that change lives - make a difference."
(Secretary General Ban Ki-moon in remarks to the General Assembly after being elected for a second term, June 21, 2011)
Ban Ki-moon is the eighth Secretary-General of the United Nations.
