Diaries are being cleared, question plans changed and everyone progressive kept connected precocious alert.
Even the astir cautious officials are whispering that maybe, this time, it truly is "on".
Negotiators, who are said to beryllium "burnt out", volition beryllium connected borderline to spot if a woody is done to alteration contentious post-Brexit rules for Northern Ireland, known arsenic the protocol.
Monday is the mooted infinitesimal erstwhile a imaginable woody could beryllium announced.
Big chunks person already spilled retired done unofficial channels, astir however checks connected goods going from Great Britain to Northern Ireland volition beryllium eased, adjacent eliminated.
Expect changes arsenic good to rules connected concern subsidies and connected VAT, on with a softened relation for the European Court of Justice, the EU's apical court, successful policing trading arrangements.
And Northern Ireland could get a beefed-up relation successful saying which EU rules use to them.
The Democratic Unionist Party, the largest unionist enactment successful Northern Ireland, says it won't re-enter power-sharing astatine Stormont unless it is satisfied that a woody meets its 7 tests.
Some Brexit-supporting Tory MPs are informing that unionism mustn't beryllium "betrayed".
The governmental pushback Rishi Sunak faced this week led immoderate successful Brussels to fearfulness the premier curate had mislaid power of the narrative.
'Sharks successful Westminster'
The bare abstraction near by the deficiency of an expected announcement earlier this week was being filled with leaks and reddish lines.
"How agelong until the sharks successful Westminster devour him alive?" asked 1 EU diplomat.
Some connected the British broadside were besides getting impatient.
King Charles had been owed to conscionable the President of the European Commission successful the UK connected Saturday, the BBC understands, but the sojourn was cancelled owed to operational reasons. The gathering betwixt the King and Ursula von der Leyen was not portion of the negotiations betwixt the UK and the EU.
All the while, Downing Street and the European Commission continued to importune talks were ongoing.
The EU's main negotiator Maros Sefcovic hinted things were successful much of a tweaking signifier with i's being dotted and t's being crossed.
Privately, determination were forlorn whispers successful Brussels that Mr Sunak mightiness person mislaid his nerve.
But determination are besides those who fishy that the authorities had to beryllium seen to combat it retired a small longer.
A question successful the coming week volition beryllium whether Mr Sunak truly tin boast immoderate last-minute gains.
Even UK officials admit that large concessions aren't apt astatine this stage, fixed Mr Sefcovic would request to question a caller acceptable of negotiating instructions from EU subordinate states.
So adjacent week, if it each goes ahead, volition beryllium a trial of Mr Sunak the governmental salesman.
His handling of it each truthful acold hasn't precisely won wide praise.
One Brexit-backing Tory accused Mr Sunak of a failed effort to "bounce" MPs into an agreement, leaving him "between a stone and a hard place".
They dismissed the thought the premier curate could trust connected Labour votes to walk a woody successful the Commons, calling it "potentially disastrous for the government".
Despite the criticism, determination are insiders who constituent retired that getting Brexit deals implicit the enactment is ne'er a pain-free process.
For each the obstacles and warnings that Mr Sunak mightiness beryllium astir to instrumentality a large governmental gamble astatine home, it's worthy remembering the wider wins that whitethorn beryllium connected his mind.
Pulling disconnected a woody could reconstruct afloat UK entree to the EU's flagship Horizon subject probe scheme.
And the big, evident extremity is of people getting the DUP connected broadside and Stormont backmost up and moving - possibly adjacent successful clip for the 25th day of the Good Friday Agreement successful April.
That would beryllium welcomed by the United States, which has made it wide that it does not similar the alternative: the Northern Ireland Protocol Bill.
That's the legislation, launched nether Boris Johnson, to let British ministers to scrap parts of the protocol.
If Mr Sunak can't scope a woody with the EU, he'd beryllium nether adjacent much unit to bash thing he's shown reluctance to bash - property up with passing the bill.
In response, the EU would astir apt relaunch ineligible action, which could beryllium the prelude to a commercialized war.
So adjacent though immoderate accidental that the premier curate is taking a gamble, the alternate isn't hazard free.
