"No force on Earth" would stop King Charles from flying to Normandy for the D-Day event, claimed a royal commentator.
This comes as King Charles embarked on his first overseas trip since being diagnosed with cancer in January, arriving at Ver-sur-Mer, Normandy earlier in the day for a UK national commemorative event for the 80th anniversary of D-Day.
Speaking to GB News, Michael Cole said: "There is no force on Earth that could have stopped the King even undergoing cancer treatment from going to Normandy today. And he's done brilliantly, as has Prince William and the Queen.
"He has obviously a personal commitment. His mother was the last head of state to have worn a uniform during World War Two."
He later added: "This 80-year commemoration anniversary is even more poignant, even more powerful, even more moving."
The King, 75, was accompanied by his wife, Queen Camilla, 76, for a D-Day ceremony in Normandy, France.
Charles did not attend the international event with world leaders on Omaha Beach later in the afternoon, with royal sources confirming that he had taken the advice of doctors who considered the ceremony "a step too far."
The King was reportedly "delighted" that his son could deputise for him for the first time.
A Palace source said: "While His Majesty’s doctors are very encouraged with the progress made so far, the King is continuing with his treatment programme - and thus we have to prioritise and protect his continued recovery.
"On that basis, each event/ day has to be carefully calibrated - and given the King’s other commitments on the day, it was advised that the international event later in the afternoon may be a step too far at this stage. He is of course delighted that the Prince of Wales will be attending to represent the nation."
Following his cancer diagnosis earlier this year, the King stepped back from public-facing duties for several months.
In April, Buckingham Palace confirmed the monarch would resume some duties, with certain engagements being "adapted where necessary".
A Buckingham Palace representative said: "His Majesty’s medical team are very encouraged by the progress made so far and remain positive about the King’s continued recovery.
"Forthcoming engagements will be adapted where necessary to minimise any risks to His Majesty’s continued recovery. The pacing of the King’s programme will be carefully calibrated as his recovery continues, in close consultation with his medical team."
Before heading to the Omaha beach memorial, William attended a ceremony at Juno beach where he hailed the "bravery and sacrifice" made by Canadian D-Day heroes.
Thousands of Canadian troops lost their lives at Juno Beach in 1944.
