Bond, a UK network for international development organisations, said it was clear the government was “deprioritising” funding “for education, gender and countries experiencing humanitarian crises such as South Sudan, Ethiopia and Somalia, and surprisingly the Occupied Palestinian Territories and Sudan, which the government said would be protected”.

“It is concerning that bilateral funding for Africa, gender, education and health programmes will drop,” Bond policy director Gideon Rabinowitz said.

“The world’s most marginalised communities, particularly those experiencing conflict and women and girls, will pay the highest price for these political choices.

“At a time when the US has gutted all gender programming, the UK should be stepping up, not stepping back.”

Unicef, a UN agency providing aid to children, said the cuts “will have a devastating and unequal impact on children and women” and called the move “deeply short-sighted”.

Philip Goodwin, Unicef UK chief executive, said: “We urge the government to adopt a new strategic approach that places vulnerable children at the heart of its aid programmes and policies…

“At least 25% of aid should be directed to child-focused initiatives, ensuring that children’s health, nutrition, education, and protection are prioritised.”

British-founded charity Street Child told the BBC that work to help children get access to education in Sierra Leone, South Sudan and the Democratic Republic of the Congo – where British aid has been a main backer – will come to an end because of the cuts.

CEO Tom Dannatt said education was the greatest long-term builder of hope, and he described reducing the support as “sad and short-sighted”.

“So children who used to go to school will not go to school, and so, more children will be found roaming the streets and ploughing fields and not developing their critical faculties,” he said.

“Whereas they should be in school learning and having a chance to build a brighter future for themselves and for their societies, but because of these cuts by British aid for the poorest children, especially in the poorest countries, that’s not the reality anymore.”

Foreign aid has come under intense scrutiny in recent years, with the one cabinet minister admitting the public no longer supports spending on it.

One organisation that escaped the cuts was the World Bank. The Foreign Office confirmed that the International Development Association (IDA), the World Bank’s fund for the world’s lowest income countries, would receive £1.98bn in funding from the UK over the next three years, helping the organisation benefit 1.9 billion people.

The Labour governments under Sir Tony Blair and Gordon Brown committed to increasing the overseas aid budget to 0.7% of national income.

The target was reached in 2013 under David Cameron’s Conservative-Liberal Democrat coalition government, before being enshrined in law in 2015.

However, aid spending was cut to 0.5% of national income in 2021 under the Conservatives, blaming the economic pressures of Covid.
