Has Prince Harry just made King Charles's visit to the US even harder? - Inside the Palace

Has Prince Harry just made King Charles' visit to the US even harder?

President Trump has hit back at Prince Harry's comments in Ukraine, declaring he "does not speak for the UK".

Just days before the US President is due to welcome Prince Harry's father to the White House for a State Visit, The Duke of Sussex delivered a powerful speech at the Kyiv Security Forum.

In it, the King's son urged the United States to honour its commitment to defend Ukraine, calling for “American leadership” to "honour its international treaty obligations" in its "enduring role in global security".

The duke said: "The United States has a singular role in this story. Not only because of its power, but because when Ukraine gave up nuclear weapons, America was part of the assurance that Ukraine’s sovereignty and borders would be respected.

"This is a moment for American leadership, a moment for America, to show that it can honour its international treaty obligations – not out of charity but out of its enduring role in global security and strategic stability."

Reporters asked President Trump for his response.

He told reporters: "I know one thing, Prince Harry is not speaking for the UK, that’s for sure. I think I am speaking for the UK more than Prince Harry.

"But I appreciate his advice very much."

The Duke of Sussex has now visited Ukraine three times since Russia's invasion of the country.

Supporting wounded veterans and serving members of the Armed Forces is clearly a passion of his.

He described himself as a "humanitarian" not a politician, echoing the words of his mother Diana, Princess of Wales during her visit to Angola with The HALO Trust in 1997.

Like his mother before him, Harry has arguably more freedom to speak his mind than he did as a working member of the Royal Family.

President Trump is right that "Prince Harry is not speaking for the UK", so what is the problem if Prince Harry goes to Ukraine as a private citizen to remind the world about the ongoing conflict there?

Well, Prince Harry is still the King's son and fifth in line to the throne, therefore his words could cause diplomatic issues.

The timing also doesn't help; King Charles will be welcomed to the White House for a State Visit in a couple of days - a chance, according to President Trump, to mend the relationship between the UK and the US.

It appears President Trump has dismissed Prince Harry's words on American defence of Ukraine.

Let's see if he brings the King's son into the conversation during private talks between the two heads of state in the Oval Office next week.

A royal endorsement for British e-racing?

I spent St George's Day with the future King of England as he championed the best of British innovation at Jaguar's racing headquarters in Oxfordshire.

Prince William was clearly in his element, celebrating the international success of a homegrown business which uses sustainable technology.

Jaguar Land Rover has a specialist team, designing and assembling race cars for Formula E - the world's first all-electric international single-seater championship.

It is the fastest-growing motorsport in the world, and I followed the Prince as he toured their state-of-the-art facilities.

He donned a headset, listening to the engineers in a racing simulator communicate with the driver.

The Prince of Wales, taller than most of Jaguar's race drivers, sat in the company's race-winning I-TYPE 7 and learned about all the secrets that help make the British team one of the best in the world.

Talking to graduates taken on by the company, he discussed how AI technology could impact the sport.

He said: “At what point does the driver become a weak link? When do you turn around and actually say get rid of the driver, we’ll put an AI person instead. We’re not far off that moment, are we? Not that we should be going down that route obviously.”

Jack Lambert, Head of Technical Integration at Jaguar TCS Racing, agreed that human drivers should not be replaced by AI.

Mr Lambert said: "AI has a place everywhere in what we do. And the way I see AI is a tool to unlock brain space for our incredible engineers. That's the way we apply it. Wanting to see racing with a driver is always what we're aiming for. But AI has a place to make our engineering capability, our understanding of what we do day to day when we go racing stronger."

The Prince was keen to learn how the technology developed for elite racing cars could one day be utilised for everyday use in cars across the nation.

Jaguar's new GT Type 00 car, which the prince was shown in the car park outside the headquarters, will use some of the technology when it is released later this year.

Let's see if customers are prepared to invest in the premium brand, and whether the tech could one day trickle down for everybody else's use.

What it was like inside the Palace reception celebrating Queen Elizabeth II?

On Tuesday, I attended a reception at Buckingham Palace, marking 100 years since the birth of Queen Elizabeth II.

The King had invited three centenarians, born on exactly the same day as Britain's longest reigning monarch, to receive their 100th birthday cards in person.

I watched on as His Majesty declared it "marvellous" that John, Joan and Mary could join him.

King Charles also helped Joan cut a specially made birthday cake, fresh from the Buckingham Palace kitchens.

The reception, held in the Marble Hallway, was packed with 200 guests - decorated using the bunting made from old curtains that used to hang in Royal residences.

It was last used for the VE Day veterans' tea party last year, held in the same room.

Every working member of the Royal Family was present, and I watched them chat with charity representatives, invited from organisations which used to have Queen Elizabeth II as their patron.

My favourite part, however, was a nod to Her Late Majesty's favourite tipple - Gin and Dubonnet with a slice of lemon.

A special cocktail had been concocted for the reception, which included Dubonnet wine.

I was told gin was not included because it was a "daytime reception".

Instead, ingredients included Dubonnet, rosemary, lemon, tonic water and ice.

I can confirm it tasted very refreshing!
