Prince Andrew 'has never criticised King Charles' despite bitter feud over Duke of York's home

It comes as Andrew is refusing to leave Royal Lodge and plans to pass his lease over to his daughters after his death.

The lease has 54 years left and the Duke intends to honour the terms of the agreement.

"I have never heard him say anything negative about his brother or indeed any member of his family," a friend of Andrew told The Sun.

"It’s just not something he would do."

However, others who have worked alongside the royal have described the 64-year-old as "rude" and "pampered".

An undercover reporter at Buckingham Palace in 2003 recalled one instance when a footman entered Andrew’s bedroom to open his curtains and said: "Good morning Your Royal Highness."

The Duke reportedly responded saying: "F*** off."

Another journalist, Valentine Low, claimed that Andrew once shouted at a royal aide.

He is thought to have said: "F*** off out of my office and f*** off out of my life."

The Prince now spends the majority of his time at his home, Royal Lodge in Windsor.

The Duke of York was told to suspend his public duties "for the foreseeable future" in 2019 - a decision made with the Queen's sign-off.

One close aide believes Andrew possibly thought he was "bulletproof" but added that others should also shoulder some of the blame for his downfall.

They said: "He’s become a pantomime figure and I understand why. He painted an easy target on his back and for the most part didn’t even realise it - or if he did, he didn’t care.

"He comes from an era where he was the Queen’s son, for God’s sake.

"He was lauded and applauded. People bowed and scraped for decades. That’s got to affect your ego and I suspect he probably thought he was bulletproof."
