Prince Harry met King Charles at Clarence House on Wednesday, in their first face-to-face meeting for 19 months.
The private tea in London, which lasted 54 minutes, comes after the Duke of Sussex publicly expressed hopes of a reconciliation with his family in an interview with the BBC in May.
After the meeting at the royal residence, Buckingham Palace confirmed that Charles and Harry spent time together.
He was driven through the gates on Wednesday afternoon after an earlier engagement at the Centre for Blast Injury Studies at Imperial College London.
The 40-year-old arrived at Clarence House in a black Range Rover at 5.20pm and left at 6.14pm, before an engagement later on Wednesday evening.
The king, who is still undergoing treatment for cancer, arrived in London from Balmoral, Aberdeenshire, on Wednesday, the penultimate day of his youngest son’s four-day trip to the UK.
On Monday, Harry laid a wreath and flowers at Windsor Castle in memory of his grandmother Elizabeth II on the third anniversary of her death, before attending the WellChild awards ceremony in London in his role as the charity’s patron.
He last saw his father in February 2024, when he travelled from his home in California to the UK to see the king after his cancer diagnosis.
The pair’s previous meeting was less than 24 hours after the announcement about the king’s health, and was without Harry’s wife, the Duchess of Sussex, and their two children.
The relationship between the duke and his father has become fraught after comments made in an interview with Oprah Winfrey, his Netflix documentary and his autobiography Spare.
Harry, who stepped down as a working royal in 2020, remains estranged from his brother William, 43, who was in Cardiff on Wednesday visiting a new mental health hub on World Suicide Prevention Day.
Charles, according to Harry, pleaded with his sons during a tense meeting after the Duke of Edinburgh’s funeral in 2021: “Please, boys. Don’t make my final years a misery.”
Senior aides to the king and Harry were pictured together in London in July, an event reported to be an initial step towards opening channels of communication between the two households.
Prince Charles will host Donald Trump at Windsor Castle for the US president’s second state visit next week.
