So after a morning with the prime minister, Joe Biden is now on his way to meet the King. So how is he getting to Windsor?

He won’t be on the 12:33 from London Waterloo, he’s travelling in the Presidential State Car, otherwise known as The Beast - and his Marine One helicopter.

Here's more about the car:

The current model - made by US car firm Cadillac - has been used since 2018, its first journey was taking Biden’s predecessor Donald Trump to New York.

The car is reinforced to protect the president from attack and also includes supplies of their blood type in case of emergency. It’s sealed against chemical attacks, and it can even use oil slicks to fend off trouble.

But for all the protection it offers, officials had to deny a previous model got stuck on a ramp in Dublin when former President Barack Obama visited the Irish capital.

After concluding his morning meeting with Prime Minister Rishi Sunak, the President Biden is headed to Windsor Castle where he will receive a royal salute and listen to the US national anthem performed by the Welsh Guards before talks with King Charles.

The two will then meet with philanthropic and financial leaders who have attended the Climate Finance Mobilisation Forum – a meeting meant to encourage efforts to increase support for developing countries to transition to renewable energy.

Here is what we know about the talks between US President Joe Biden and Prime Minister Rishi Sunak at Downing Street this morning:

• During Biden's first visit to No 10 as president, he told Sunak he "couldn’t be meeting with a closer friend and greater ally”
• Despite clashes over Washington supplying Ukraine with cluster munitions and Ukraine Nato membership, Biden insisted the UK-US relationship is "rock solid"
• Sunak said it was “great for us to carry on our conversation” and the leaders would consider how to strengthen cooperation and joint economic security

Biden tells Sunak that he “couldn’t be meeting with a closer friend and a greater ally”.

There are some contentious issues between the two allies – such as the provision of cluster bombs to Ukraine – but Biden insists that there is no problem in the transatlantic ties.

We're hearing more snippets of Rishi Sunak's talks with Joe Biden in the Downing Street garden.

The prime minister said it was "great for us to carry on our conversation" after a series of meetings this year, including last month's visit to Washington.

Sunak said the pair would consider "how do we strengthen our co-operation and joint economic security to the benefit of our citizens".

Both leaders are due to attend the Nato summit in Lithuania, which starts tomorrow.

Sunak continued: "We stand as two of the firmest allies in that alliance and I know we'll want to do everything we can to strengthen Euro-Atlantic security."

Speaking at his Downing Street meeting with Rishi Sunak, US President Joe Biden says that the US-UK relationship is “rock solid”.

We heard from national security adviser of the United States Jake Sullivan on Friday, who gave us some insight into what President Biden hopes to achieve this week.

• On meeting with King Charles: “He will engage with a forum that will focus on mobilising climate finance, especially bringing private finance off the sidelines.”
• On meeting with Rishi Sunak: “To consult on a range of bilateral and global issues.”
• On the Nato summit: “They will discuss a range of subjects from strengthening Nato's eastern flank to modernising its deterrence and defence capabilities.”
• On Ukraine joining Nato:“Ukraine will not be joining Nato coming out of this summit.”

Rishi Sunak travelled to Washington last month for talks with President Biden.

One memorable moment was when Biden called Sunak “Mr President”. He corrected himself and said he had “just demoted” the prime minister.

Biden went on to joke that the pair would be able to solve all the world's problems in "the next 20 minutes".

When President Biden and King Charles settle down for a cup of tea at Windsor Castle later, it will be their first meeting since the Coronation.

There were some claims about Biden not going to the Coronation as being a snub, but in fact it would have been more unusual if he had attended.

No US president has ever gone to a Coronation. It’s never been a convention that they attend and the First Lady Jill Biden went on his behalf.

Both Joe and Jill Biden had been at the late Queen’s funeral last September.

Biden also hasn’t been dodging trips to the UK, quite the opposite. In terms of US presidential visitors, Biden is already one of the most frequent to the UK.

This will be his fifth trip, more than Donald Trump or Ronald Reagan and equal with Barack Obama and George W Bush.

Bill Clinton remains the president who came most often to the UK.

This is what Downing Street looks like just before the president of the United States rolls up.

Busy.

The red carpet gets rolled out - literally.

And then a bloke with a brush turns up to brush it.

Rishi Sunak flew into Washington in June for talks with President Joe Biden.

Ahead of the talks, Sunak laid a wreath at the Tomb of the Unknown Soldier in Arlington National Cemetery.

Sunak also attended the Washington Nationals versus Arizona Diamondbacks baseball game in the US capital.

He apparently declined to throw the ceremonial first pitch and - after the UK and US anthems were played by a military band - said to Nats manager Dave Martinez: "They should put a (cricket) bat in my hand… that's more my thing."

At the end of the visit Sunak and Biden unveiled the Atlantic Declaration with the aim to strengthen economic ties between the UK and the US.

It is not a full trade deal but Sunak said the agreement would bring benefits “as quickly as possible”.

Back in the UK, opposition Labour leader Sir Keir Starmer said Sunak had failed to meet one of his party's key pledges.

The media is getting ready for the president’s arrival, but they’re not the only ones gearing up.

Earlier, Larry the cat was on the No 10 doorstep. He is Downing Street's chief mouser and has been a resident of the building since 2011, after being adopted by then-Prime Minister David Cameron.

Was he waiting patiently for Joe Biden to show up? Or just enjoying some early morning sun?

Either way, Downing Street is preparing for this morning’s visit from President Biden, stay with us for updates.

Good morning and welcome to our coverage of US President Joe Biden’s flying visit to the UK as he makes his way to the Nato summit which starts tomorrow in Lithuania.

Biden is meeting Rishi Sunak this morning. These two are getting quite familiar with one another - it’s the fifth time in as many months they have met.

On Friday, the United States announced it would be sending cluster bombs to Ukraine. This hasn’t gone down well in the UK - it’s one of 123 countries which have signed up to an international treaty which bans their use and production - so this could be something the pair discuss.

And then it’s an audience with the King this afternoon as Biden travels to Windsor Castle. Remember, President Biden didn’t go to his Coronation back in May, First Lady Jill Biden and his granddaughter were there in his place.

We’ll be following Biden’s movements all day so stay with myself, Ali Abbas Ahmadi and Andre Rhoden-Paul as we bring you all the updates.
