Anwar’s candidature has been swirling around diplomatic circles in Malaysia, but he said he had yet to even discuss the post with his family.
"There are many qualified candidates and I’m just looking at that," said Anwar.
"Right now I’m committed by my work with accountability and to Georgetown University and meeting up with friends here in Malaysia," he added.
The new secretary general is nominated by the UN Security Council, with its five permanent members, Britain, China, France, Russia and the United States playing a crucial role in the decision.
The nomination then would have to be confirmed by the whole 191-nation UN General Assembly.
