Ugandan diplomat Olara Otunnu has become the seventh candidate to join the race to become the next leader of the United Nations.
The former UN under-secretary-general, who served as a special representative for children and armed conflict, was nominated by Kampala on Friday.
A previous opposition presidential candidate, he also served as Uganda's UN envoy, and as his country's foreign minister for a brief period.
At 75, he is the oldest of the current candidates to replace Antonio Guterres whose mandate as secretary-general comes to an end on 31 December after two five-year terms in the post.
The other potential successors in the running are from Chile, Ecuador, Argentina, Costa Rica, Guyana, and Senegal's Macky Sall.
