The embattled head of Oxfam GB has resigned in the wake of a scandal over sexual misconduct by its staff in Haiti and other disaster zones.
Mark Goldring, who resisted pressure to step down amid outcry in February, said he was proud of the charitys work over the past five years.
But I think the time is coming for a new leader, he added. Following the very public exposure of Oxfams past failings, we have redoubled our efforts to ensure that Oxfam is a safe and respectful place for all who have contact with us.
We are now laying strong foundations for recovery. I am personally totally committed to seeing this phase through.
Mr Goldring, who will leave his post when a successor is recruited, said that 2019 will see Oxfam rebuild and renew to help tackle poverty and respond to crises including the wars in Yemen and Syria.
I think that this journey will best be led by someone bringing fresh vision and energy and making a long-term commitment to see it through, he added.
Caroline Thomson, the chair of Oxfam, said she had accepted Mr Goldrings decision with great sadness and with thanks for his dedication and leadership.
Mark faced the test of a lifetime managing the crisis which hit us in February and related to events before he joined, she added. He rose to the immense challenge and his leadership has been invaluable through it.
It is testament to his integrity and humility that Mark will see through the next few difficult months.
Ms Thompson described Oxfam as a great institution representing the best of British values as it works to regain support lost from both politicians and the public.
