In today's Budget speech, Chancellor George Osborne kept to his promise and announced that 0.7% of the UK's national income will be spent on international aid.
That means increased support from Britain for millions of children around the world, including for countries in crisis like Syria.
David Bull, UNICEF UK's Executive Director said:
"Today is a historic day for the world's poorest children and a proud day for Britain. Keeping our promises to the world's poorest children and their families is both the right thing to do and is in Britain’s interests."
The announcement is a huge success for the Enough Food for Everyone IF campaign, a movement of more than 150 charity organisations, including UNICEF UK, who have come together to campaign to end world hunger.
George Osborne's promised increase in international aid was a key campaign issue for the IF coalition.
"Aid has already saved millions of children's lives around the world, and for that we should all hold our heads up high," said David Bull.
Right now, British aid is helping UNICEF to deliver nutrition, safe drinking water, vaccines, education, clothing and protection to millions of children affected by the crisis in Syria.
Bull added: "By providing this much needed support, UNICEF, with the help of British aid, is helping to ensure Syria’s children do not become a lost generation. This is a clear example of British aid working hard for those that need it most."
