“There’s a long road ahead, but a channel of communication is now open for the first time in years,” another source told the Mail.
“There was no formal agenda, just casual drinks. There were things both sides wanted to talk about.”
It’s unclear which side reached out first to book the catch-up, and it’s understood no one from Prince William’s team was present.
“The King has consistently shown he loves both his sons and, as he has done in the past, is prepared to meet Harry when their diaries allow,” a source told the Mail.
“It’s not unusual for aides from different households to meet, especially when there is a new influx of staff starting, but this is a significant moment.
“If there is a period of calm and reflection on the part of the duke, then there be a way forward for him to begin along the road of repairing his relationship with his father.”
In September, Harry is expected to return to the UK to attend the annual WellChild Awards, of which he is patron, providing a potential opportunity for the pair to meet in person for the first time in 18 months.
They last saw each other back in early 2024, when Harry made a quick dash back to London to see his father shortly after he revealed his cancer diagnosis.
If Harry and the King arrange a reunion, it would mark a significant turning point in the ongoing feud between the duke and the royal family, which was sparked before Harry and Meghan sensationally quit official duties and moved to the US.
The Mail on Sunday reported last month that Harry “agreed that the Invictus Games should extend an invitation to his family”, as revealed by a source.
If accepted, it would mean Harry could be pictured with his estranged family for the first time since 2022.
