Charles will deliver the opening address at the Commonwealth heads of government meeting (CHOGN) on Tuesday, after Prime Minister Andy Burnham said he was "open" to offering the association of 56 member states the opportunity to discuss a slavery apology from Britain.
As the head of the Commonwealth, it would not be appropriate for Charles to talk about UK government policy during his speech in Antigua and Barbuda, and he will not be apologising there, according to Sky's royal correspondent Laura Bundock.
On whether he could offer an apology in the future, Ms Bundock said that the conversation in this respect "has shifted forwards significantly".
The King's words at the summit will focus primarily on encouraging solutions to global challenges and opportunities for the "family of nations".
Some Caribbean countries made further calls for Britain to apologise for its role in selling enslaved people, and for reparations, before the King left the UK for his nine-day tour of the region, which has included a state visit to Guyana and a trip to the Bahamas.
Ahead of the visit, it was understood ministers had not advised Charles to offer an apology or reparations, in keeping with established policy.
But the potential for an apology was then thrown back into focus when Mr Burnham wrote in the Guardian on Friday: "We are offering a structured dialogue with those affected by the transatlantic slave trade.
"Listening to calls for a formal apology on behalf of the British state will form an important part of this process and I am open to them."
The prime minister expressed his "sorrow and regret for the pain and suffering of so many millions" but ruled out financial reparations.

A Buckingham Palace spokesperson said: "As we have indicated, the King will not shy away from confronting the most shameful aspects of the past during this visit.
"You may therefore expect him to address them in his speech with unflinching honesty, sincere sorrow, and respect for the wider discussions that will be taking place between relevant governments on this issue at CHOGM and beyond.
"He will be speaking at CHOGM in his capacity as head of the Commonwealth. It would not be appropriate for him to address matters of particular policy relating to the UK government's position.
"In keeping with the CHOGM agenda of 'Accelerating Partnerships and Investment for a Prosperous Commonwealth', His Majesty's speech will therefore primarily focus on encouraging practical solutions and united efforts to address global challenges and opportunities relevant to all 56 members of the Commonwealth family today."
The palace was told of Mr Burnham's change to the government's position on a slavery apology in a timely manner, and there has been no need for alterations to the King's speech or his CHOGM programme after the article.
Charles started his nine-day visit last Tuesday by acknowledging the "great suffering of the past" in a speech at a youth rally in the Bahamas.
Ahead of his visit to Guyana, the nation's president Mohamed Irfaan Ali said Charles had recognised slavery as the "darkest days in human history", but an apology would be "the next step".
Before departing from Guyana on Friday, the King visited Independence Park in the capital, Georgetown, where 33 people involved in the Demerara Rebellion of 1823 were hanged.
The Queen arrived in Antigua a few days ago and was joined by Charles late on Friday night, with the couple enjoying a rest day together on Saturday.
Of the CHOGM event, with the wording of the speech now set to come under heavy scrutiny, a senior palace aide said: "His Majesty is well practised on the diplomatic tightrope, as you've seen again several times this year. He is up for challenging visits with complex issues and relationships in play.
"He sees it as his role to 'bat for Britain', the realms and wider Commonwealth, promoting, protecting and enhancing relationships at the highest level."
States of Jersey Police said in an earlier statement there had been a "multi-agency response" to reports of multiple drones operating close to the airport on Friday evening.
It said the first report was received at around 8.20pm on Friday, with reported drone activity continuing until about 10.30pm.
Searches were carried out across several areas in the west of the island, but no drone operator has yet been identified, police said on Friday.
Three inbound aircraft were initially diverted and one of the three was eventually able to land safely in Jersey at around 11.45pm, the force added. The diverted flights were from Gatwick, Heathrow and Southampton.
Jersey Airport said in a statement late on Saturday evening there had been further flight disruption caused by drone activity.
It said: "Due to the illegal and persistent drone activity around the airport on Saturday evening, regrettably four flights were not able to land as scheduled.
"Airlines are now making alternative travel arrangements directly with passengers to get them to Jersey as quickly as possible."
Flights from Heathrow and Southampton airports were cancelled on Saturday evening.
Jersey Airport asked passengers hoping to travel on Sunday morning to check with their airlines for flight updates.
The statement from the airport added: "Our first priority is the safety of passengers, crew and public.
"We also fully appreciate the significant disruption, concern and frustration that this illegal activity has caused passengers, their families, friends and colleagues."
Meanwhile, Jersey's chief minister, Senator Lyndon Farnham, said in a statement: "The deliberate and unlawful operation of drones in the vicinity of Jersey Airport over the past two evenings has caused significant disruption to passengers, airlines and airport operations.
"I would like to thank the teams from Ports of Jersey, States of Jersey Police, Air Traffic Control, the emergency services and all those involved for their swift and professional response to an extremely challenging situation.
"Their first priority has rightly been the safety of the travelling public and aircrew."

He added: "The government and our operational partners are treating these incidents with the utmost seriousness."
Mr Farnham said police investigations are ongoing and "every available avenue is being pursued" to identify those responsible.
He continued: "We are also working closely with UK authorities and specialist agencies to explore additional operational support, enhanced detection capability and counter-drone technology.
"People should be under no illusion about the seriousness of these actions.
"Operating a drone close to an airport is not a prank or a harmless hobby. It puts public safety at risk, disrupts critical transport infrastructure and can have significant consequences for hundreds of travellers and businesses.
"To those responsible, the message is clear: if you are identified, you should expect to face the full consequences of the law."
Mr Farnham reassured members of the public that Jersey Airport remains safe and that "lessons from these incidents will be acted upon swiftly".
He added: "Our airport is a vital lifeline for the Island. We will not tolerate behaviour that jeopardises its safe operation or undermines public confidence in our transport infrastructure."
Anyone with information about people operating drones around the island on Saturday evening, or who may have witnessed drones land or take off, has been asked to contact States of Jersey Police.
Mohammad el Shami had been detained by the Houthi militant group since 6 June 2024, UN High Commissioner for Human Rights Volker Turk said in a statement.
His family said they had only been notified of his death recently, more than one month after it occurred, and had not been informed of the cause or circumstances, according to Mr Turk. There was no immediate comment from the Houthis.
The UN Human Rights office said they were "utterly devastated", adding that it is a "heartbreaking loss" and the family deserves to know the truth.
Mr Turk on Saturday called for a prompt, independent and thorough investigation, and demanded the immediate and unconditional release of all other UN personnel under Houthi detention.
These include seven staff members from his office, humanitarian workers, and civil society members.
Yemen's prime minister condemned the death and said he held the Houthis fully responsible.
He said more than 70 UN employees and dozens of humanitarian workers are still being detained.

The group has said those being held were part of a spy network working for the US and Israel.
The Houthis have also accused humanitarian organisations of using their work as a smokescreen for intelligence activities, without providing evidence.
The Houthis seized the capital Sanaa in 2014, sparking a Saudi-led military intervention in 2015 in support of Yemen's internationally recognised government.
The conflict has since divided the nation, with the Houthis holding Sanaa and much of the north and northwest, while government-aligned forces control much of the south and east.
The Saudi-led coalition fighting in Yemen said early on Saturday that it had intercepted and destroyed a drone over its oil-rich Eastern Region as attacks by Yemen's Iran-aligned Houthis group continue.
The conflict between the two sides has grown more intense in recent weeks, opening a destructive new front in the wider US-Israeli war on Iran.
Last month, there was a string of Houthi attacks on Saudi airports, including on Riyadh airport, one of which killed at least 13 people and wounded over 300.
On Wednesday, Saudi-led airstrikes struck a crowded market in northern Yemen, killing 14 people and wounding 15 others, a Houthi health official said.
The strikes hit a central market near a gas station in al Hazm, the capital of al Jawf province, around midday while it was filled with shoppers, said Anees al Asbahi, spokesperson for the Houthi-run health ministry, in a post on X.
Also on Wednesday, the Ministry of Transportation of the internationally recognised government said the Houthis had launched two ballistic missile strikes on Aden airport, according to a statement on the ministry's website.
The lawsuit brought by Mr Trump against the newspaper and its owner Rupert Murdoch related to a story the Journal published last year, which said a letter featured Mr Trump's name and was included in an album compiled for Epstein's 50th birthday in 2003.
It represented Mr Trump's second attempt to sue the Wall Street Journal, and was dismissed with prejudice on Saturday, meaning the dismissal is permanent.
The letter - bearing what appeared to be Mr Trump's name - includes text framed by the outline of what appears to be a hand-drawn naked woman and ends with, "Happy Birthday - and may every day be another wonderful secret," according to the newspaper.
Mr Trump denied writing the letter, calling the story "false, malicious, and defamatory". The White House maintains the signature is not Mr Trump's and that it looks different from his distinctive full signature, NBC News says.
Dismissing the case at a federal court in Miami, District Judge Darrin Gayles ruled that the president did not prove the defendants made defamatory statements with actual malice, as required by law.
Mr Trump was "grasping at straws", the ruling said, and attempted to "manufacture" flaws in the paper's reporting.
The paper's "thoughtful and detailed investigation" was commended by the judge.

The letter was reportedly collected by Ghislaine Maxwell as part of a birthday album for Epstein years before he was first arrested in 2006.
The lawsuit accused the paper and its reporters of having "knowingly and recklessly" published "numerous false, defamatory, and disparaging statements" which, it alleged, causing the president "overwhelming financial and reputational harm".
Mr Trump had refiled the lawsuit and was seeking at least $10 billion in damages.
The 35-year-old was charged with offences including two counts of possessing explosives under suspicious circumstances, and possession of a prohibited weapon (discharge of electricity or noxious gas).
The Police Service of Northern Ireland (PSNI) said in a statement: "Detectives from the Police Service of Northern Ireland's Terrorism Investigation Unit have charged a man to court in connection with offences under the Explosives Act and Firearms Order.
"The charges follow searches at properties in both the Shankill Road and Edwina Street areas of north Belfast on Friday, 30th and Saturday, 31st October."
Detective Chief Inspector McCallum said: "Following these searches a number of suspicious devices, along with other items were located and seized by officers for forensic examination.
"Local residents who were evacuated as a precaution have now been allowed to return home following the public safety operation conducted alongside Ammunition Technical Officers (ATO)."

He added: "This evening, Saturday 31st October, we have charged a 35-year-old man to court with offences including two counts of possessing explosives under suspicious circumstances, and possession of a prohibited weapon (discharge of electricity or noxious gas)."
The man is due to appear before Belfast Magistrates' Court on Monday 2 November.
