Another Commonwealth country has flagged a possible move towards ditching the British monarchy, saying the country is "not totally free" with a British head of state.
Barbados replaced Charles' mother, Queen Elizabeth II, with an elected president in 2021 and Jamaican Prime Minister Andrew Holness used a royal visit last year to announce his country planned to become fully independent.
Now, Just days after the coronation, Terrance Drew, the Prime Minister of Saint Kitts and Nevis, pointed towards a similar path and suggested an apology should come from the monarchy for its historical role in the slave trade.
"And so, that aspect of it is telling us that we are not totally free yet.
"That consultation or discussion will start some time during my leadership."
Drew told Britain's national broadcaster his country, two Caribbean islands with a population roughly the size of Wagga Wagga, would benefit from becoming a republic.
"We still have the same colonialist thinking," he said.
"And that is one thing we have to move away from."
Charles last month backed research into the monarchy's links to slavery, following an investigation by The Guardian.
"This is an issue that His Majesty takes profoundly seriously," Buckingham Palace said in a statement.

"As His Majesty told the Commonwealth heads of government reception in Rwanda last year: 'I cannot describe the depths of my personal sorrow at the suffering of so many, as I continue to deepen my own understanding of slavery's enduring impact'."
As well as celebrations, Britain's first coronation for seven decades sparked protests and criticism from republicans in the UK and many of the 14 so-called "realms" that retain the King as their head of state.
In London, protesters were arrested with "not my king" placards and Down Under, the Australian Republican Movement used the occasion to highlight the "ridiculousness" of bowing to a king on the other side of the world.
First Nations representatives from 12 nations, including Australia, called for the King to address colonial wrongs such as slavery and stolen land and cultural artefacts.
Among those was ex-Greens Senator, who said Thursday Charles should "begin a process of repairing the damage of colonisation, including returning the stolen wealth that has been taken from our people".
Australian Prime Minister Anthony Albanese, joined in an oath of allegiance to the King, favours ditching the monarchy but has ruled out holding a referendum during his current three-year term, instead prioritising the Indigenous Voice to parliament.
On Saturday, soldiers carrying flags from the Bahamas, South Africa, Tuvalu and beyond marched alongside British troops in a spectacular military procession in honour of the monarch.
For some, the scene affirmed the ties that bind Britain and its former colonies. But for many others in the Commonwealth, Charles' coronation was seen with apathy at best.
In those countries, the first crowning of a British monarch in 70 years was an occasion to reflect on oppression and colonialism's bloody past.
The displays of pageantry in London jarred especially with growing calls in the Caribbean to sever all ties with the monarchy.
"Interest in British royalty has waned since more Jamaicans are waking to the reality that the survivors of colonialism and the holocaust of slavery are yet to receive reparatory justice," the Reverend Sean Major-Campbell, an Anglican priest in Jamaican capital Kingston, said.
The coronation was "only relevant in so far as it kicks us in the face with the reality that our head of state is simply so by virtue of biology", he said.
As British sovereign, Charles is also head of state of 14 other countries, though the role is largely ceremonial. These realms, which include Australia, Canada, Jamaica, Papua New Guinea and New Zealand, represent a minority of the Commonwealth nations: most of the 56 members are republics, even if some still sport the Union Jack on their flags.
During the Caribbean trip Prince William and Kate, Princess of Wales, took last year, the heir said the relationship between the monarchy and the Caribbean has evolved.
The royal family would "support with pride and respect your decisions about your future," he told a reception in the Bahamas.
