Save the Children UK has appointed Justin Forsyth as its new chief executive.
Forsyth most recently worked as a special adviser on international development to Gordon Brown when the latter was Prime Minister. Forsyth was previously director of campaigns and policy at Oxfam.
He replaces Jasmine Whitbread, who has taken on the newly created role of international chief executive of Save the Children. Forsyth will start in September.
Alan Parker, executive chairman of Save the Children, said: "This is a critical period for Save the Children UK. We have made great progress in recent years, but the challenge of supporting children abroad and at home continues to grow.
"He brings enormous experience and commitment and I have no doubt he will make a real contribution to driving the organisation forward."
Forsyth said in a statement he was excited to take up the role.
