Mark Drakeford is preparing outline the Welsh government's £25bn spending plans that volition instrumentality Wales into 2026.
Wales' concern caput volition people the budget, which impacts the system and immoderate taxes paid by radical and businesses, connected Tuesday afternoon.
But with Labour conscionable abbreviated of a bulk successful the Senedd, a woody indispensable beryllium struck with different enactment successful bid to get it through.
Here's what to look retired for.
NHS waiting database 'crisis'
First Minister Eluned Morgan made a large admittance precocious erstwhile she called record-long waiting times for NHS attraction "a crisis".
Reducing the backlog of operations created by Covid was the Welsh government's apical precedence aft the pandemic.
Three years aboriginal - the bulk of which Morgan was wellness curate - and much radical than ever are waiting.
Health volition swallow fractional this budget, which covers the play up to the adjacent Senedd predetermination successful 2026.
But Mark Dayan, a argumentation adept astatine the Nuffield Trust, says it takes clip to amended things.
"What I deliberation we've seen, some erstwhile waiting times improved earlier successful the '00s and successful immoderate of the cautious improvements we've seen elsewhere successful the UK, is adjacent erstwhile you commencement to crook things astir it takes a truly agelong play of clip earlier the magnitude of weeks the mean idiosyncratic volition beryllium waiting is truly importantly changing," helium said.
An other £1bn
In October, Chancellor Rachel Reeves gave the Welsh authorities an other £1bn to walk successful this budget.
It puts them successful "a antithetic world" aft a agelong play of spending squeezes and precocious inflation, says Drakeford.
Experts astatine Cardiff University accidental it should let for a boost to NHS spending without having to raid different departments.
But the representation is not truthful rosy aft 2026, which could make hard decisions for nationalist services successful the not-too-distant future.
Social care
Most of those services are tally by Wales's 22 section authorities, immoderate of whom person issued dire warnings astir their finances.
Social care, schools, bin collections, libraries and swimming pools are each provided by councils, which get astir of their backing from Drakeford.
Yawning gaps person appeared successful their budgets and it's not wide however immoderate volition balance the books.
Their leaders reason the NHS cannot beryllium sorted retired unless societal attraction is fixed.
But the companies delivering attraction accidental there's hardly capable backing to wage unit the Real Living Wage that the Welsh authorities wants.
Soon they volition besides person a bigger National Insurance measure arsenic a effect of the UK government's Budget.
Cost of living
Drakeford is chuffed Reeves has fixed him much to spend, but each week successful the Senedd opponents onslaught different large decisions she has taken.
They see means-testing pensioners for the wintertime substance outgo and maintaining the two-child benefits cap.
The Scottish government has offered to supply assistance for radical affected.
Even though the Welsh authorities does not person the aforesaid powers implicit the benefits strategy arsenic Scotland, it volition inactive look calls to assistance radical with the outgo of living.
It does, however, person immoderate powers implicit tax, including implicit a information of income taxation and the onshore transaction taxation you wage erstwhile buying a home.
They could springiness ministers immoderate much wealth to spend. Lots of businesses saw their rates spell up aft the past budget.
But hiking income taxation would beryllium a immense decision. The Welsh rates haven't changed since they were devolved successful 2019.
Will Wales' fund pass?
Because it has less than fractional the seats successful the Senedd, Labour can't marque this fund a world unless it tin person astatine slightest 1 subordinate from different enactment to backmost it successful a important ballot adjacent year.
We tin expect a batch of dialog and bargaining down the scenes, if it hasn't started already.
Morgan has tried to up the ante, with a blood-curdling informing astir the wealth Wales loses if her fund fails to pass.
Losing votes could besides lop 10p disconnected each £1 of income tax, depriving the Welsh authorities of important funds.
That mightiness entreaty to some, but it would correspond a governmental and fiscal situation for the Senedd – and it's hard to spot a authorities surviving that.
Drakeford says the draught of his fund volition connection a "bright aboriginal for Wales".
The Welsh Conservatives said societal attraction needed much funding, arsenic did the NHS "which is astatine situation point".
Tory shadiness concern curate Peter Fox besides called for a "root and subdivision reappraisal truthful that taxpayers' wealth is well-spent and efficiently allocated".
The enactment of the Welsh Liberal Democrats' sole MS, Jane Dodds, would beryllium capable to walk the budget.
Her spokesperson said she wanted much backing for societal care, kid poorness and agrarian investment.
The past 3 budgets passed arsenic portion of a co-operation woody with Plaid Cymru, which has present ended.
Plaid concern spokesperson Heledd Fychan said the archetypal curate should "fight for a just deal" from Keir Starmer's UK government.
"If she fails, past Labour's fund volition mean much cuts and NHS backing that delivers ever-diminishing returns," she said.
