“That’s what I saw in my time, and why you have a whole lot of private secretaries to the Prince of Wales walking.
“The Prince of Wales didn’t want to hear impartial advice; he wanted to hear people agreeing and he’s always been a bit like that," the source said.
They went on to reveal details of the Prince's sometimes formidable temper.
“The Prince of Wales has a fearsome temper.
“It’s never been directed at me, but I’ve seen several members of the Royal Family break down and cry in my presence over the years.
“They are human beings like everyone else, with tempers; fury in inbuilt in several of them.”
When the Duke of York left the Royal Navy in 2001, the Prince of Wales extended an offer of employment to his younger brother.
Prince Andrew was asked if he wanted to become an aide to the future king, which he turned down.
"Andrew could have been the one member of the family that Charles relied on," a source told Royal Central. Instead, he accepted an offer from senior Labour MP Peter Mandelson to become an international trade emissary for the government.
Prince Charles was also said to be angered by Prince Andrew's appointment as trade envoy.
"My understanding is that Prince Charles was less than happy that Andrew was given the role of Trade Envoy back in 2001 after he left the Navy," royal correspondent Robert Jobson told Vanity Fair.
In 2011, however, Prince Andrew's friendship with convicted sex offender Jeffrey Epstein forced him to stand down from his position.
