About 7,000 people have cancelled regular donations to Oxfam over the past 10 days, the charity's chief executive has told MPs.
The wave of cancellations has come after allegations were published in The Times newspaper on 9 February that in 2011 Oxfam workers in Haiti had sexually exploited victims of the 2010 earthquake and that the charity had subsequently failed to pass on the full details of the misconduct to the relevant authorities.
Mark Goldring revealed the figures during a hearing in front of the International Development Select Committee in parliament this morning, at which Stephen Twigg, chair of the committee, announced that the group of MPs would be launching a full-scale inquiry into the scale of sexual exploitation in the aid sector.
"I think about 7,000 individuals have cancelled regular donations to Oxfam over the past 10 days," said Goldring.
He said corporate partners were "reserving judgements".
He said: "They want to look at what we have done, what our procedures are, how their particular relationship might have been compromised and what we’re setting in place for the future."
Goldring, who apologised repeatedly for the charity's failings, said 26 new cases of sexual misconduct had been internally reported to Oxfam GB since the story broke, and these were a mixture of ongoing and historical cases, of which 16 had taken place outside the UK.
He said he encouraged anyone with a story to come forward and Oxfam would investigate all historical cases if the Charity Commission believed it was warranted.
Twigg said the terms of reference of the inquiry would be published in the near future.
