Liz Truss has landed on her first overseas visit as Prime Minister as politics creeps back to life following the 10-day national mourning period.
In the hours after the Queen's funeral, the Tory leader flew to the United Nations' general assembly in New York - an event that will be dominated by the energy crisis and the war in Ukraine.
The Prime Minister is holding meetings with world leaders, including her first bilateral with the US President Joe Biden after cancelling talks in No10 on Sunday.
She also faces an awkward meeting with Emmanuel Macron, after suggesting in the Tory leadership contest the "jury's out" on whether the French president is a "friend or foe" during the Tory leadership contest.
After returning to Britain, Ms Truss will have just hours to sign off Chancellor Kwasi Kwarteng's long-awaited mini-Budget, which the new chancellor will deliver in the House of Commons on Friday.
He is expected to reverse April's hike in national insurance despite the fact it will benefit the rich more than the poor, and scrap a planned hike in corporation tax - costing billions of pounds.
The chancellor will also set out how the Treasury will fund the energy price cap - expected to cost around £100billion - after Ms Truss omitted the crucial detail when she unveiled the package hours before the Queen's death.
Here The Mirror looks at the week ahead.
Tuesday: Politics stopped for the Queen’s funeral, but not for long. Hours afterwards Liz Truss was taken to the airport to leave for the UN General Assembly in New York, landing at around 2am UK time.
Held every September, it is her first major outing on the world stage as PM and see issues like the Ukraine war, energy crisis and influences of Russia and China surge back onto the agenda.
She will also have her first full bilateral meeting with US President Joe Biden, though there'll be no time for a White House visit.
While Liz Truss gets a diplomatic whirlwind under way in New York, things take a little longer to get back to normal in the UK. Parliament will not be sitting as the massive operation to allow the Queen lying in state is dismantled.
But expect a rush of government statements that were held back due to the mourning period. They could include a fracking report - already leaked - that casts doubt on Liz Truss’s decision to lift the ban on drilling.
A ministerial reshuffle could continue, with dozens of government jobs vacant. But appointments need approval by the King, and it was unclear when that would happen as he has another week of mourning.
Meanwhile this week TSSA and RMT unions, which had called off their rail strikes due to the Queen’s death, could announce rescheduled dates. Aslef has already scheduled strikes that will disrupt the Tory conference (below).
Wednesday: If the Queen had not died we would have got the first outing of the deputies at PMQs - possibly Therese Coffey versus Angela Rayner.
Instead MPs will form a queue (yes, another one) to swear an oath to the King while Liz Truss is in New York. There will be no PMQs.
The release of pent-up government statements will continue. Business Secretary Jacob Rees-Mogg is expected to announce desperately-awaited details of energy bills help for businesses after a two-week delay.
But it's thought his plan will need an Act of Parliament, so can only be implemented in mid-October at the earliest after a shortened party conference recess. Help may have to be backdated, leaving stricken businesses to find the cash now.
Thursday: Parliament will sit again properly for the first time in two weeks, as Liz Truss flies back in from New York.
Her deputy Therese Coffey - the new Health Secretary - is likely to give a statement on the stricken NHS, focusing on her plan to cut ambulance delays and shorten backlogs.
But she’ll face questions over how the package is funded, after Ms Truss vowed to divert billions from the NHS into social care.
Meanwhile there could be a rush of Urgent Questions and debates on issues that reared their heads over the mourning period, from Tory ministers wanting to scrap the cap on bankers’ bonuses in the middle of a cost of living crisis, to the UK decision to keep suspending post-Brexit checks on good crossing the Irish Sea.
Friday: Chancellor Kwasi Kwarteng will deliver his mini-Budget, with the National Insurance and corporation tax cuts Liz Truss promised in the leadership campaign. Reports suggest the national insurance cut could be brought forward to November payslips.
The mini-Budget could also give more detail of how much their energy bills plan might cost (for the first few months), scrap the cap on bankers' bonuses in the middle of a cost of living crisis, and review 'fiscal rules' which restrict how much the government borrows.
It could announce "special investment zones" in up to 12 UK areas, with speculation the areas will cut personal taxes, tear up affordable housing quotas and even water down environmental pledges to get firms building. Expect fears over runaway capitalism.
And it could announce a series of tax reviews. The Sunday Mirror revealed Liz Truss wants to allow the transfer of all personal tax allowances between married couples and civil partners where one earns below the £12,570 tax-free threshold. Currently a lower earner can “gift” £1,260 of allowance – saving £214 tax after adjustments - but that could rise tenfold.
But a huge political row is brewing over the PM's failure to spell out how she'll pay for her plans, other than more borrowing. This could overshadow her bid to focus on the sunlit uplands of “more growth”.
Saturday: Delegates arrive in Liverpool for Labour ’s party conference - if they can get a golden ticket on Avanti’s cut-back train services, that is.
MPs, who usually get a couple of days’ run-in, will have little to no time to get back to their constituencies in between the “fiscal event” and the four-day meeting, which begins properly on Sunday.
Sunday and beyond: Keir Starmer kicks off Labour conference with a likely interview by one of the Sunday TV shows, such as Laura Kuenssberg.
He will give his keynote speech on the following Tuesday as he focuses on getting Labour election-ready and - his critics hope, at least - putting flesh on the bones of policies the party can fight for on the doorstep.
There could be more rows with the left over issues like whether to visit picket lines or support electoral reform. Liz Truss then has her turn the following week at Tory conference laden with ideology.
She has vowed to unveil a crackdown on striking workers by October 5 - or at least, she had vowed to before the Queen died. By coincidence, not only is October 5 the day of her keynote speech in Birmingham; it’s also the day an Aslef train strike will leave thousands of Tories struggling to get home.
Reports suggest Rishi Sunak's plan to cut income tax in 2024 could be brought forward, but that this would only happen in a 'full-fat' Budget later this winter.
