Andrew always denied the allegations - but the repeated accusations would not go away.
And his associations risked real reputational damage to the Royal Family.
His friendship with convicted paedophile Jeffrey Epstein, his dealings with an alleged Chinese spy, and then the posthumous publication of his accuser, Virginia Giuffre's memoir.
Her family said she brought down a British prince with her truth and extraordinary courage.
The piling pressure was starting to overshadow the work of Andrew's wider family. And with the Prince of Wales soon heading to Brazil for his Earthshot award, enough was enough.
We understand the Royal Family, including Prince William backed the King's leadership on this matter.
The King made the decisions, his family supported them.
Andrew will leave Royal Lodge, his large home on the Windsor estate. His ex-wife, Sarah Ferguson, who also lived there, will "make her own arrangements".
It was their family home for many years. Both daughters, Princess Beatrice and Princess Eugenie, who grew up there, will keep their titles.
As for Andrew, he will soon move to Sandringham - the King's private Norfolk estate - where the family traditionally gathers for Christmas; and he will be funded privately by the King.

This is all a formal process carried out in consultation with official authorities, but the government supports the decision taken.
This will not have been easy for the King, but he knew he could not ignore public opinion. The criticism and anger directed at Andrew was never going to stop - and only he had the power to take the ultimate action against his own brother.
For years, Andrew enjoyed the perks and privileges of his powerful position, but his birthright could not withstand withering public disdain.
And now he's paid the ultimate price.
