The United Nations' 193-member states are expected to appoint Portugal's former Prime Minister Antonio Guterres as the world body's next secretary-general.

Peter Thompson, president of the General Assembly, said in a statement that he hoped Guterres would be approved by a unanimous vote on Thursday.

Guterres was nominated by acclamation in the 15-member Security Council last week to replace Ban Ki-moon whose second five-year term ends on Dec. 31.
