Energy Secretary Ed Miliband is said to be defying Sir Keir Starmer over Net Zero cuts to fund defence.
Mr Miliband is resisting calls to cut spending on Net Zero which would equate to at least one per cent of capital budget savings, according to sources.
The cuts would fund the long-awaited Defence Investment Plan (DIP), which Sir Keir said yesterday in PMQs would be published before the next Nato assembly in a few weeks time.
No10 might forcefully cut spend in the Department of Energy Security and Net Zero (Desnz) by hundreds of millions of pounds, cutting funding for hydrogen production and heat pumps.
However, it is said the Prime Minister wants to go further and cut spending on carbon capture and storage, which has a budget of £9billion, but has never been proven to be commercially viable.
The Energy Secretary's defiance could cost defence investment, a Whitehall source told the Telegraph.
They said: "While investing in sustainability is clearly important, it is also unsustainable to leave Britain’s wind farms vulnerable to Russian attack."
This comes after Kemi Badenoch in the House of Commons yesterday focused her questioning on the absence of the DIP and how the Government intends to fund defence spending.
Hilary Benn: 1,000 illegal migrants removed from Northern Ireland last year
Northern Ireland Secretary Hilary Benn addressed the Common Travel Area between Ireland and the UK which was utilised by Hadi Alodid to seek asylum in Belfast.
He said, speaking to GB News, the agreement has benefitted Irish and British people but people have used it as a loophole to enter the UK illegally, which the Government is "already working very closely with the Irish authorities to prevent abuse of the Common Travel Area".
Mr Benn said: "In the last year alone, 1000 people have been removed from Northern Ireland because they do not have the right to be here, and it is that intelligence-led operation, including on major travel routes, airports, bus routes, train routes, and ports, that is the most effective thing that we can do, because the common travel area underpins, of course, the Good Friday Agreement."

“Where your neighbours, where your colleagues, where your classmates are sitting intimidated and in fear, are having their homes attacked and their livelihoods destroyed.
“That is totally unacceptable and it is not British.”
He said more needs to be done in "protecting" borders into the UK.
James Cartlidge fears he will be in a 'zimmer frame' before Defence Investment Plan is published
Shadow Defence Secretary James Cartlige said he might be in a "zimmer frame" before the Government's Defence Investment Plan is published.
Speaking to GB News, he said: "I have nightmares that years from now, I'll be standing at the despatch box with my zimmer frame saying to the Secretary of State, 'when are they going to publish a Defence Investment Plan?' Because I've been asking it for so long. I've asked it in every oral questions for months.
"We've got the threats from the war in Ukraine and the war in the Middle East - it's extraordinary all this delay and dither. The Government really does need to get a grip."
