Sorry, Mr Moon

The post of United Nations Secretary-General is not exactly a low-profile job.

But the world's top diplomat, Ban Ki Moon of South Korea, is struggling for name recognition more than a year after taking over from Kofi Annan.

Ban's chief of staff, Vijay Nambiar, sent a memo to staff worldwide dealing with "the question of ensuring clarity and accuracy in the recognition of his name."

The letter said: "Many world leaders ... still use his first name mistakenly as his surname and address him wrongly as Mr Ki-moon or Mr Moon."
