A senior United Nations aid official is being investigated over allegations that he tried to suppress a “food-for-sex” scandal during one of the world’s biggest refugee crises.

Craig Sanders, a deputy director with UNHCR, the UN refugee agency, is accused of ordering a female colleague not to report the alleged rape of a refugee by an aid worker at a camp in Chad during the Darfur crisis in 2004.

Lori Handrahan claims Mr Sanders told her in a rage that he would not have “a sex-for-food scandal on my watch”.
