KING Charles clashed with Prince William after he refused to stop flying his entire family in a helicopter, it has been claimed.
Charles, 75, made his son sign a “waiver” taking responsibility for threatening the succession by getting airborne with Kate and the kids, it is said.
The monarch “echoed” the concerns of the late Queen — who we revealed urged William to quit flying after her ’copter was grounded by a fault — after his cancer diagnosis.
William, 42, who described flying a chopper as “better than anything”, is said to have brushed off the pleas and continues to ignore an unwritten rule barring senior royals from taking to the air together.
The trained RAF pilot has previously flown Kate, 42, George, 11, Charlotte, nine, and Louis, five, the 115 miles from Kensington Palace in London to their family home in Anmer Hall, Norfolk.
He also flew for the East Anglia Air Ambulance for two years and, in 2021, borrowed a £5.4million chopper to keep his flying hours up for his pilot’s licence.
A flight disaster for the Cambridges would put Prince Harry, 39, on the throne.
Royal author Robert Jobson wrote: “After being diagnosed with cancer, King Charles, perhaps reminded of his own mortality, echoed his late mother’s concerns.
“When William refused to stop flying with his family, Charles insisted that he sign a formal document, acknowledging the risks involved and taking full responsibility for his actions.”
In ‘Catherine, The Princess of Wales: The Biography’, Mr Jobson added: “It would be scant consolation, of course, for an unspeakable tragedy, let alone for the prospect of King Harry and Queen Meghan.”
The King and his mother’s concerns stem from helicopter scares.
Her Sikorsky S-76 suffered a fault in August 2021 and a flight was aborted.
Sophie Wessex was in a near-miss in 2017 and, in 2019, Camilla, then the Duchess of Cornwall, came within 200ft of an aircraft in the Queen’s chopper before it later had to avoid a glider.
Kensington Palace refused to comment on the waiver claims or whether Wills was still flying his family.
