Rachel Reeves will set out her spending plans for the coming years this afternoon in a Costs Review expected to lay the course for significant tax increases.
But it is likewise likely to include squeezes for other departments as the Chancellor seeks to keep within the straight jacket of fiscal guidelines she has set for herself.

Her room for manoeuvre has also been more constrained by the Government's U-turn on winter season fuel payments, which will see the benefit paid to pensioners getting as much as ₤ 35,000 each year at a cost of around ₤ 1.25 billion to the Treasury.
Among the anticipated losers are the cops, with Yvette Cooper's pleas for more cash to aid with reducing crime thought to have fallen on deaf ears, regardless of warning it might cause fewer bobbies on the beat.
Chancellor Rachel Reeves is prepared to reveal real-terms boosts for the service every year, however there are worries that it may not be enough.
However the Home Secretary is apparently to be placated with more than half-a-billion pounds to plough into reinforcing the UK's borders - including drones to spot migrants in the Channel.
The complete details will be revealed in the Commons, but several announcements have actually already been made.

₤ 445 million for upgrades to Welsh railways.

Among the anticipated losers are the police, with Yvette Cooper's pleas for more money to help with lowering criminal activity believed to have fallen on deaf ears.
WINNERS
The NHS
Among the primary announcements is expected to be a ₤ 30 billion boost in NHS financing, a rise of around 2.8 percent in genuine terms.
The money injection, which amounts to ₤ 17 billion in genuine terms, follows Sir Keir Starmer vowed to ensure that by the next election 92 percent of patients in England waiting for scheduled treatment are seen within 18 weeks of being referred.
The Institute for Fiscal Studies has actually currently warned that any increase in NHS financing above 2.5 per cent is most likely to imply real-terms cuts for other departments, or further tax rises to can be found in the spending plan this autumn.
Latest NHS data recommends around 60 percent of people are currently seen in this time and figures released last month showed the overall variety of clients on waiting lists had actually increased a little from 6.24 million to 6.25 million.
But it comes just 9 months after The NHS was a major winner from Ms Reeves's very first Budget last October, when the Chancellor as she poured ₤ 22.6 billion more into the flatlining health service.
At the time Health Secretary Wes Streeting was extremely clear that this might not suffice, since the NHS is 'not just on its knees, it's on its face'.
Schools
A senior minister exposed at the weekend that schools are set to get a financing increase in the costs review.
Technology Secretary Peter Kyle said the Government will commit to investing 'the most we've ever spent per student'.
Facing questions from broadcasters on Sunday about which civil services will be prioritised, Mr Kyle stated 'every part of our society is struggling' and numerous sectors had actually asked Chancellor Rachel Reeves for more money.

The Institute for Fiscal Studies (IFS) said state school budgets will stay 'very tight' and universities will not reach a 'safe and secure monetary footing' in 2025/26.
This is despite Labour's new VAT on private school fees, which will pay for 6,500 brand-new instructors, and a university tuition cost rise of ₤ 285 to ₤ 9,535.
Earlier today the National Education Union called for a 2 per cent wealth tax to be used to put more cash into education.
General secretary Daniel Kebede said: 'Our schools are at breaking point, with cuts resulting in less resources, bigger class sizes, and the erosion of subjects that are important to a well-rounded education. The Government must stop short-changing education.
'Now is the time for a wealth tax, and closing unreasonable loopholes to ensure the extremely wealthiest pay their reasonable share. Instead of choosing the pockets of our pupils, it's time to tax profits and prioritise our children and our communities over business greed.'
Defence
Defence costs is expected to be increased as the federal government reacts to the growing military hazard from Vladimir Putin's Russia.
It comes days after the NATO secretary general alerted that Britain's only option to investing more in the armed force would be to start finding out Russia.
Former Dutch PM Mark Rutte provided the cooling message while in London for talks with Sir Keir ahead of a NATO summit later this month.

A more 1.5 percent of GDP would be required for 'defence-related expense' under Mr Rutte's strategy to reinforce the alliance.
It follows pressure from US President Donald Trump on European members of NATO to hike their military budget plans.
There are questions about how the UK would fund such a big increase - roughly comparable to an extra ₤ 30billion yearly.
Britain allocated 2.33 percent of GDP to defence last year, and Sir Keir has only dedicated to reaching 2.5 percent by April 2027.
The Labour Government has an 'ambition' of increasing that to 3 percent in the next parliament - likely to go to 2034.
Social housing
Other statements anticipated on Wednesday include ₤ 39 billion for social and economical housing over the next decade as the Government aims to meet its target of building 1.5 million brand-new homes by the next election.

Flagship preparation reforms which are 'critical' to the homes promise cleared the Commons last night.
Angela Rayner is leading efforts to build 1.5 million brand-new homes by the next election.
The Treasury stated this would see yearly financial investment in budget friendly housing increase to ₤ 4 billion by 2029/30, almost double the average of ₤ 2.3 billion in between 2021 and 2026.

But Tory shadow housing secretary Kevin Hollinrake described the draft legislation as 'unsafe' and warned it might lead to 'rows of uninspiring concrete boxes'.
In addition, the 200-year-old law criminalising rough sleepers is to be scrapped in what homeless charities have actually hailed a 'landmark minute'.
The Vagrancy Act, presented in 1824 for penalty of 'idle and disorderly individuals, and rogues and vagabonds, in England', is to be repealed by spring next year, the Government has actually verified.
LOSERS
The authorities
Reports suggest she will get an above-inflation increase for forces at the cost of other parts of her department, but questions stay over whether it is enough.
On Monday, West Midlands Police and Crime Commissioner (PCC) Simon Foster called for the reinstatement of 700 officers the force has actually seen cut given that 2010, while Hertfordshire's PCC Jonathan Ash-Edwards alerted the force is facing a growing problem.
