FORMER prime minister Theresa May has backed a growing bid by Conservative rebels to force Boris Johnson to reverse his widely-criticised cuts to foreign aid.

His Conservative predecessor heaped pressure on the Prime Minister to avert a Commons revolt as the number of Tory MPs to back a rebel amendment doubled to 30.

May’s former deputy Damian Green and Johnny Mercer, who recently resigned as defence minister, also added their names to an amendment led by former international development secretary Andrew Mitchell.

Johnson has been criticised across the political spectrum for temporarily reducing foreign aid from 0.7% of national income to 0.5%, breaking a manifesto commitment.

The National:

Mitchell has tabled an amendment to the Advanced Research and Invention Agency (Aria) Bill, a piece of legislation which establishes a new “high-risk, high-reward” research agency backed with £800 million of taxpayers’ cash to explore new ideas.

The amendment, if selected by Commons Speaker Sir Lindsay Hoyle and approved by a majority of MPs, would force any shortfall of the 0.7% foreign aid spending target to be made up by Aria’s budget.

The Bill returns to the Commons for further consideration on Monday.

Mitchell said: “More and more of my colleagues in the House of Commons are supporting this move to to stand by our manifesto promise.

“With our economy returning to growth, there is no justification for balancing the books on the backs of the world’s poor.

“With G7 leaders coming to Britain next week, there is an opportunity for us to reclaim our rightful place on the global stage.

“Britain’s national interest is not being served by the devastating impact these cuts are already having on the ground and the unnecessary loss of hundreds of thousands of innocent lives.

“We urge the Government to think again.”

The Government has blamed economic damage caused by the Covid-19 pandemic for its aid decision.
