A senior member of the United Nations has made a blistering attack on the Secretary-General Ban ki-Moon's leadership.
Inga Britt Ahlenius is the outgoing head of a body charged with combating corruption and misconduct within the UN.
In a report leaked to an American newspaper, she accuses Mr Ban of undermining her efforts and of leading the UN into an era of decline.
The BBC reports the leaked report reflects acrimony over power struggles within the UN's internal affairs office. Mr Ban's chief of staff rejects the accusations.
