It may be the Coronation of King Charles, but at his crowning in a few weeks, eyes will also be on his warring sons Prince William and Prince Harry.
Buckingham Palace confirmed earlier this week it was pleased to announce that Harry will be part of the congregation inside Westminster Abbey to see his father King Charles crowned on May 6.
Harry's attendance will see him appear in a public setting with his brother, sister-in-law Kate and the rest of his family for the first time since he lambasted the royals in his memoir Spare.
He accused William of physically attacking him in his tell-all book, which was published in January.
The title of the memoir relates to the fact that William, as the older brother, is the heir to the throne, while Harry is not - and is the spare.
But it seems their late mother Princess Diana may have thought that it would be Harry who would be better suited for the top job - and even gave him a secret nickname.
It was been claimed that William often confided in his mum that "he didn’t want to be king”.
A young Harry is said to have cheekily replied on one occasion: "If you don’t want the job I’ll have it."
According to royal expert Robert Jobson, this led to Diana privately calling Harry GKH - or Good King Harry.
He told the Channel 5 programme William & Harry: Princes At War?: “She used to refer to Harry as GKH (Good King Harry) because she thought he’d probably be better equipped for the role in the future than William.”
Meanwhile, TV broadcaster Jeremy Paxman also said Diana talked about her sons' futures during a lunch meeting.
He explained: "We talked about our children and she said William often told her that he didn’t really want to be king, and then Harry would say, ‘If you don’t want the job I’ll have it'."
It comes as sources claimed that William still feels betrayed by the contents of Harry's book Spare.
However, it is believed that when Harry comes to the UK in a few weeks' time, he will stay at Frogmore Cottage for one last time, which is just 700 yards from William and Kate's Windsor home of Adelaide Cottage.
But one source told the publication that the gulf between the brothers is so big - it cannot be seen how their relationship will ever be repaired.
Meanwhile, when it comes to the ceremony itself, the princes will be sat so far apart that cameras will not be able to get a direct shot of the pair together, according to the Daily Express.
Any potential smirks, sideways glances or awkward stares won't be broadcast to the entire world.
Due to the tensions within the Royal Family, Harry's arrival at Westminster Abbey will be meticulously crafted down to the exact minute.
The Palace will be hoping to avoid any awkward confrontations, so are allegedly putting Harry several rows back behind the senior royals.
It's believed he will be sat with other non-working members of the Royal Family and those he has no bad blood with, such as Princess Beatrice and Princess Eugenie and their husbands.
It has been rumoured that some royals will give Harry the cold shoulder, as many cannot forgive him for his repeated accusations against the family.
