For the first time since 2010, Britain officially has a Labour prime minister.
Rishi Sunak, too, is due to meet with the king in London before giving his resignation speech.
There is much to learn and reflect on, and I take responsibility for the loss.

Sir Keir Starmer talks at a campaign event on June 29, 2024, in London.
Read Starmers full victory speech, below.
You campaigned for it; you fought for it; you voted for itand now it has arrived.
And it feels good, I have to be honest.
Four and a half years of work changing the party.
This is what it is for.
A changed Labour Partyready to serve our country, ready to restore Britain to the service of working people.
And I want to thank each and every one of you here campaigning so hard for change.
And not just in this campaign either, also for these four and a half years changing our party.
The Labour movement is always everythings achieved, past and future, down to the efforts of its people.
So thank you truly.
You have changed our country.
A mandate like this comes with a great responsibility.
Our task is nothing less than renewing the ideas that hold this country together.
It should always respect your contribution and we have to restore that.
To return politics to public service so that politics can be a force for good.
Make no mistake, that is the great test of politics in this era.
The fight for trust is the battle that defines our age.
It is why we campaigned so hard on demonstrating we are fit for public service.
Service is the precondition for hope, respect, the bonds that can unite the country.
Together, the values of this changed Labour Party are the guiding principles for a new government.
Country first, party second.
That is the responsibility of this mandate.
You know, 14 years ago, we were told that were all in it together.
I say to British people today: imagine what we could do if that were actually true.
So by all means, enjoy this hope.
Nobody can say you havent waited patiently.
Hold onto it, because it is what unity is made for.
That we will serve them faithfully, govern for every single person in this country.
But also: dont forget how we got here.
This morning, we can see that the British people have voted to turn the page on 14 years.
But dont pretend that there was anything inevitable about that.
Theres nothing preordained in politics.
Election victories dont fall from the sky.
Theyre hard won and hard fought for.
And this one could only be won by a changed Labour Party.
We have a chance to repair our public services, because weve changed the party.
We have the chance to make work pay because we changed the party.
Country first, party second isnt a slogan.
Its the guiding principles of everything we have done and must keep on doing.
On the economy, on national security, on protecting our borders.
The British people have to look us in the eye and see that we can serve their interests.
And that work doesnt stop now.
The changes weve made are permanent, irreversible, and we must keep going.
We ran as a changed Labour Party and we will govern as a changed Labour Party.
I dont promise you it will be easy.
Changing a country is not like flicking a switch.
But even when the going gets toughand it willremember, tonight and always, what this is all about.
Now, I may have mentioned my parents a few times in this campaign, once or twice.
It is a hope that may not burn brightly in Britain at the moment.
But we have earned the mandate to relight the fire.
That is the purpose of this party and of this government.
We said we would end the chaos and we will.
We said we would turn the page and we have.
Today we start the next chapter.
Begin the work of change, the mission of national renewal and start to rebuild our country.
