Commons Speaker Sir Lindsay Hoyle says he will accept applications for an emergency debate on the matter to be held on Tuesday.
Boris Johnson has narrowly avoided a rebellion by some of his own MPs over cuts to the foreign aid budget – but there will be a Commons debate on the issue tomorrow.
Thirty Tories, including former prime minister Theresa May and four other ex-cabinet ministers, had backed a rebellion against the £4bn reduction and had hoped to force a vote on the matter.
But Commons Speaker Sir Lindsay Hoyle ruled the amendment, proposed by Conservative former minister Andrew Mitchell, was “not in scope” of the Advanced Research and Innovation Agency Bill.
Noting that MPs have not had a chance to debate the matter, Sir Lindsay did however say he would accept applications for an emergency debate on the matter.
Mr Mitchell later successfully applied for a debate, telling the Commons: “Parliament has not had its say on this vital matter.”
The debate on Tuesday will last for up to three hours, although any vote at the end of it will not be binding on the government.
The proposed amendment had intended to make the government commit to reinstating the 0.7% aid target from next year – from the funding for this agency if it is not met through alternative means.
