William and Kate married in 2011 at Westminster Abbey after an eight year courtship ad have since produced three royal children, Prince George, Princess Charlotte and Prince Louis.
However they briefly split for a few months in 2007, with unearthed accounts suggesting William chose to break up with his stricken future-wife over the phone.
A former colleague of Kate’s told the Mirror: “Around the middle of the day, she was pacing the car park outside the office on her mobile.
“A few people noticed because it’s a pretty unusual thing to do.
“She’d deliberately gone outside to take the call because she didn’t want to be overheard.
“Kate was walking up and down and looking upset as if she was having an argument, but she didn’t cry.
“Word went round that it was William and they were having problems – now it’s clear what it was all about.
The colleague added: “When she came back to the office she didn’t say a thing and disappeared for the rest of the day – she hasn’t been back to work since.
“When someone asked where she was, they were told she was sick, yet she hasn’t been marked sick in the book.
“We didn’t think anything about it at the time, but looking back, the call was definitely a girlfriend-boyfriend tiff.”
It then became public that William and Kate had broken up.
Royal experts at the time speculated that William wanted to concentrate on his life as a young officer, believing it could be his last opportunity to enjoy himself before taking on more senior royal commitments.
Of course, the couple soon patched things up and were eventually married in a ceremony watched by a global audience of 162 million viewers and have become immensely stable figures in the Royal Family in a year that has seen the death of Prince Philip.
On Tuesday the couple shared a condolence post on social media claiming they had received “great comfort” from the public support after the “difficult” loss of the Duke of Edinburgh.
The post published on Instagram said: “Their Royal Highnesses have been incredibly moved by the many thoughtful messages they have received in recent weeks.
“They will all miss their much loved grandfather and great-grandfather, but your message has provided great comfort at this difficult time.”
The year also saw Prince Harry and Meghan Markle’s alleged tension with the family ignited by a bombshell two-hour CBS interview with Oprah Winfrey.
The couple spoke of alleged racism suffered in the UK by Meghan and the couple’s son Archie, and claimed they had felt “hounded” by the media.
An unautharised biography, Finding Freedom, claimed that the Duke and Duchess of Sussex believe the Royal Family did not take accountability for the concerns raised in the interview.
