Prince Andrew, Duke of York was summoned to Sandringham to face "strong words" from the Prince of Wales, a week after a similar meeting with his father.
Duke had to drive 140 miles to the Queen's Norfolk estate from his home at Windsor for the discussion on Monday, hours before a Panorama interview with Virginia Roberts Giuffre piled more pressure on the Duke.
It is thought the Prince, 71, wanted to reinforce the Queen's wish his 59-year-old brother step back from royal duties "for the foreseeable future".
The Duke of Edinburgh, 98, who has been staying at Home Farm, Sandringham, was also in the meeting to agree the move. A week earlier, with the Prince of Wales still on tour overseas, the Duke of York had been summoned for a meeting with his father.
"It was a tense meeting and Philip told his son he had to take his punishment," said a Sandringham insider.
