Bulgarian Prime Minister Boiko Borisov has announced that the government is nominating its European commissioner, Kristalina Georgieva, as candidate to be United Nations Secretary-General.

The decision Wednesday came two days after the Bulgarian UNESCO chief, Irina Bokova, was in sixth place in the Security Council's latest informal poll.

Earlier this month Borisov had said that his government would continue backing Bokova's candidacy only if on Sept. 26 she was among the top two candidates.

"We made huge efforts, not only the government, but also the president, the foreign ministry and Irina Bokova herself, but you see the result," Borisov said at the government meeting.

In order to be replaced, however, Bokova would need to file a letter announcing her withdrawal. She has said she sees no reason to do that.
