It is thought that William was incensed about Harry’s comments to the BBC, in which he said he did not know how long his father had left to live after being diagnosed with cancer. William was said to find the comments deeply offensive and insensitive.

The brothers have barely spoken in the past two years following the publication of Harry’s bombshell memoir, Spare, in which he revealed how he and William had come to physical blows and had been sibling rivals for decades. William was also deeply upset when Harry revealed that Kate had not been welcoming to Meghan, and there had been an issue when Meghan had asked to borrow Kate’s lip gloss.

William is understood to have been against his father meeting with Harry this week, because he is fearful that private family conversations will not remain confidential. Though Harry revealed intimate details of family conversations in Spare, King Charles believes it is time to move on and wants to bring Harry in from the cold.

As Vanity Fair reported this week, while Charles is open to a truce, the ball is in Harry’s court: He must prove to his father that he can be trusted.

Meanwhile, Harry hopes that this latest visit to the UK will lead to him being able to return more often if the issue over his security can be resolved. After losing a High Court case and appeal for government-funded police protection, Harry, no longer a working royal, has to fund his own protection. However, this week’s visit showed he can work and travel safely in the country.

While in the UK, Prince Harry traveled to Windsor and Nottingham as well as around the capital, carrying out official engagements with a number of his charities, including WellChild, The Diana Award and the Invictus Games. On Friday, Harry made a surprise visit to Ukraine on his way home in a show of solidarity to the country. Accompanied by a team from the Invictus Games Foundation, Harry visited Kyiv and met with veterans to outline how the charity plans to help wounded soldiers.

It marks his second visit to the country this year. Both times Harry was invited by the Ukrainian government.
