[JURIST] UN High Commissioner for Refugees Ruud Lubbers [official profile] submitted his letter of resignation to UN Secretary-General Kofi Annan Sunday, citing a lack of confidence in him due to allegations of sexual harassment [JURIST report]. Saying that the sexual harassment claims could not be substantiated, Lubbers wrote "For more than four years I gave all my energy to UNHCR. Now in the middle of a series of problems and with ongoing media pressure you apparently view this differently…. To be frank, and despite all my loyalty, insult has now been added to injury and therefore I resign as high commissioner." Lubbers wrote that he will continue to serve until a successor is confirmed by the UN General Assembly. AP has more.
