The transference of power in the UK may be peaceful, but it's by no means dull.

At first light, the world's press wedged themselves in tightly, vying for the best spot to witness history. Scaffolding has been erected along one side of Downing Street, to fit even more cameras, lights and journalists, penned in behind barriers. 

This little street, in the heart of Westminster, is like a film set. Lights and cameras galore.

And at 11am…. Action. 

For Sir Keir Starmer, the outgoing PM, that walk from the door of Number 10 to the podium must have felt like an eternity. The man who vowed to stay put, forced out by a party who now stood behind him, clapping. And smiling.

His speech was short of the emotion journalists love on these occasions. No tears, no cracking voice. Just a resolute determination to leave with dignity.

"I go with good grace," he told the cameras. "I go with a smile. And I go proud of everything we have achieved. Thank you very much."

And just like that, the Starmer years were over. One final task though. And it's an important one.

The transfer of power doesn't happen until the King grants it. First, Starmer, arriving at Buckingham Palace to resign. Then the new man, Andy Burnham, meeting King Charles III to accept a Royal request to form a new government. It's a ceremony known as "The Kissing of the Hands". These days though, no Royal hand gets kissed.

And finally, the new Prime Minister arrived in Downing Street, to smiles and hugs. A very long hug with his Mother, waiting on the street to see her son cheered into Number 10. 

No lectern for the new man. His speech was off the cuff, note-free, and landing a tone of hope: "Britain needs to show the world that we can regain our stability once again. And that is our challenge, to make politics work. To make politics better."

He promised a 10-year plan to get the country on its feet again. He promised a new way to do politics. And he promised to end homelessness. 

And, as journalists pore over every word to satiate their networks, that work is only just beginning. 

Behind that famous black door, cabinet picks are being finalized, policy pored over. And the journalists are still in their pens, notebooks at the ready.

It's been a long day. It will be an even longer night.
