Prince Philip committed a huge mistake years ago that cost him his relationship with Prince Charles. Until today, the royals are reportedly distant towards each other.

The Duke of Edinburgh always thought that his eldest son was a softy, and as such, he decided to send him to Cheam and then to Gordonstoun. But instead of improving Prince Charles’ personality, the heir to the throne suffered a lot while during his school years.

While speaking with Express, royal expert Richard Fitzwilliams said that Prince Philip’s decision impacted Prince Charles and their relationship negatively.

“One of the main reasons for the distant relationship between the Duke of Edinburgh and Charles was the decision, made by the Duke, to send him firstly to Cheam and then to Gordonstoun. In Jonathan Dimbleby’s authorized biography of Charles, the Duke is quoted as writing ‘Children may be indulged at home, but school is expected to be a spartan and disciplined experience in the process of developing into self-controlled, considerate and independent adults.’ This was a bad mistake,” he said.

Fitzwilliams went on to say that Prince Philip was given the power to choose which school his children will be sent to by Queen Elizabeth II. This way, he would be kept busy.

“The Queen deferred to the Duke in the matter of their children’s education as Prince Philip’s early years as Consort were not easy, especially for someone with his dynamic personality. He failed to recognize that Charles, a sensitive child, would not flourish in the schools where he himself had been in his element,” he said.

When the Queen Mother was still alive, she wanted Prince Charles to study at Eton, but her opinion was shunned away by Prince Philip. Prince Charles and his two younger brothers, Prince Andrew, and Prince Edward also went to the same boarding school.

Years after his graduation, Prince Charles said that there were some benefits to studying at Gordonstoun even though he initially saw it as hell on earth.
