Oxfam’s deputy chief executive has resigned over the handling of a sex scandal involving aid workers.
The British charity is accused of concealing the findings of an inquiry into claims staff used prostitutes while delivering aid in Haiti in 2011.
Penny Lawrence said she was “ashamed” and takes full responsibility.
Oxfam – which denies a cover-up – has met with the International Development Secretary in a bid to prevent its government funding from being cut.
Mark Goldring, chief executive of Oxfam GB, thanked Ms Lawrence for her service and said he “deeply respected” her decision to accept personal responsibility.
Ms Lawrence joined Oxfam GB in 2006 as international programmes director, leading teams across 60 countries, according to the charity’s website.
“Concerns were raised about the behaviour of staff in Chad as well as Haiti that we failed to adequately act upon,” she said in a statement.
“It is now clear that these allegations – involving the use of prostitutes and which related to behaviour of both the country director and members of his team in Chad – were raised before he moved to Haiti.”
The allegations emerged in The Times on Friday, which said Oxfam’s country director for Haiti, Roland van Hauwermeiren, used prostitutes at a villa rented for him by Oxfam in the aftermath of the 2010 earthquake.
According to the paper, Oxfam knew about concerns over the conduct of Mr van Hauwermeiren and another man when they worked in Chad before they were given senior roles in Haiti.
Oxfam said allegations that underage girls may have been involved were unproven.
