UK deploys King Charles as its secret political weapon

A senior royal aide has described King Charles as "a secret weapon" that the British government is increasingly deploying to handle politically charged diplomatic situations.

The remark came after the monarch completed a nine-day tour of the Caribbean that included a meeting of the Commonwealth of Nations.

The aide spoke on condition of anonymity, which is standard practice for palace briefings about sensitive matters.

"It's a great secret weapon to send the king," the aide told reporters.

The aide added that Charles was "able to reach the parts that, dare I say, politicians probably couldn't quite have reached."

This is a striking admission because the British monarch is constitutionally required to stay out of politics.

King Charles became head of state in September 2022 upon the death of his mother, Queen Elizabeth II.

His constitutional role is largely ceremonial and symbolic.

But in practice, as Britain's global influence has diminished, successive governments have turned to the crown to lead diplomatic efforts.

The Caribbean tour was dominated by one issue above all others: slavery.

Specifically, whether Britain and the king should formally apologize for the transatlantic slave trade and offer to pay reparations.

Charles did neither in his public speeches, following British government policy.

But he did express what he called "profound personal sorrow" about the horrors of slavery.

Speaking at the opening ceremony of the Commonwealth Heads of Government Meeting in Antigua, Charles called the slave trade a "shameful chapter of history" that "fills my heart with horror and my soul with the most profound personal sorrow."

Commonwealth leaders broadly welcomed this as a positive step forward.

The 56-nation Commonwealth includes many countries that were former British colonies.

Many of those nations have been pressing Britain for a formal apology and financial reparations.

The king's careful wording allowed him to acknowledge the pain without crossing the line the government had drawn.

The senior aide described the tour as "complex and challenging."

But the aide said Charles "had demonstrated his statecraft both by word and deed."

The aide also revealed that this is part of a clear pattern.

"We're just in the fifth year of the reign," the aide said.

"I think what we're seeing is a very clear pattern emerging of the government asking the king to head into quite politically charged situations, quite challenging situations."

Dealing with difficult diplomatic tasks is something Charles relishes, according to the aide.

"Refreshing and reinvigorating relationships with nations where there have been some complex political issues at play, that is what he lives and breathes for," the aide said.

This is not the first time Charles has been deployed in this way.

Amid tensions with US President Donald Trump — most recently over the Iran war — the British government enlisted Charles to help smooth relations.

The king hosted Trump on a state visit in the UK.

Charles then paid a reciprocal state visit to the United States.

These are the kinds of high-level diplomatic gestures that heads of government typically handle themselves.

But the British government calculated that Charles could achieve outcomes that Prime Minister Keir Starmer could not.

The Caribbean tour involved around 40 engagements across the Bahamas, Guyana, and Antigua and Barbuda.

Charles is approaching his 78th birthday on November 14.

He continues to undergo cancer treatment, having been diagnosed in early 2024.

Despite this, the aide said the king coped well with the punishing schedule.

During a Junkanoo parade in the Bahamas, Charles spontaneously joined in, shaking cowbells and dancing in nearly 40-degree Celsius heat.

"The King said, 'I think I'm going to get involved,' and off he went and did," the aide recalled.

"At the end of it, they said, 'Could they have the cowbells back?' Because perhaps they might want them as a special souvenir for the next Junkanoo."

The aide used this moment to address questions about Charles's health.

"I think probably the best response to that is a picture of a man about to turn 78 wangling the cowbells as he jives down the street in nearly 40 degree heat," the aide said.

"When the engagement finished, I get in the car next to him and say: 'Crikey, I'm hot.' He says, 'Oh, never mind.' So no, he copes. I mean, frankly, he copes better with it than I do, and I'm younger than him."

The aide added: "This is literally what he was born to do, he's very good at it, and he enjoys the reaction he gets from people in the doing of it."

The tour marks a high point in what has been another difficult year for the monarchy.
