Many people never thought this day would arrive, but when King Charles and Queen Camilla were crowned together at Westminster Abbey, it marked the beginning of a new era for the British monarchy.

One of the most notable royal scandals of the previous century was the affair between King Charles and Queen Camilla during the new king's first marriage, as per The Mirror. This affair had a huge impact on Camilla's popularity for several years.

In the past, the two individuals had been intimately linked with one another before Charles's first marriage to the late Princess Diana; nonetheless, they separated at some point. In a magnificent royal wedding at St. Paul's Cathedral, Camilla married Andrew Parker Bowles and had two children, Tom and Laura. Charles married Diana Spencer, a member of the Spencer family at the time.

Despite this, King Charles and Queen Camilla later resumed their relationship. Princess Diana asserted that they had been engaged to one another since the beginning of his relationship with his first wife. Princess Diana was still alive at the time. She expressed during her lifetime how much anguish this affair caused her, from purchasing Camilla costly gifts to using specific nicknames for each other.

In an interview with BBC's "Panorama," she explained that "there were three of us in this marriage, so it was a bit crowded." This statement brought Diana a great deal of notoriety.

Even though Diana was much younger than both King Charles and Queen Camilla, and she admitted to struggling with mental health issues during her marriage, she still stood up for herself and her marriage, according to a former royal protection officer. Diana reportedly referred to this as the "bravest moment" in her marriage later on.

Ken Wharfe stated in an interview with ITV that the confrontation occurred at a party Camilla's sister was hosting. He said that Camilla's sister was having a party. It surprised everyone that Diana, who was the Princess of Wales at the time, opted to go to the event because none of her close friends were there.

Wharfe said, "Diana didn't have any particular friendships at that party but when we arrived there, it was almost like freeze-framing a scene in a movie because there was this surprise that Diana had even arrived."

About an hour after this awkward-sounding entrance to the party, Diana called over for her personal protection officer: "I went out, and there was Diana, who said, 'You've got to come with me. I can't find my husband or Camilla. 'Now, I couldn't say no. Clearly, this woman was in some distress, and eventually, we found the Prince and Camilla sat on a sofa in the basement of this property just talking."

Diana then confronted Camilla directly for the first time, Wharfe claimed. "I didn't know quite what Diana was going to do at that point, but, with a great deal of confidence, Diana just went up to both of them and said to Camilla, 'Please don't treat me like an idiot; I know what's going on.'

"And Camilla sort of said something, to which I still to this day I have never really understood what she meant by that, which is 'well, you know, you have two wonderful boys.' Well, it was an incredible moment for me and certainly for them. That was a defining moment in their life because I think at that point... this was an indicator the end was nigh."

King Charles and Princess Diana eventually separated in 1992, and in 1995, the couple's divorce was finalized - only two years later, Diana died in a tragic car accident in Paris. In 2005, Camilla and Charles married in a civil ceremony in Windsor, and she became the Duchess of Cornwall.

Meanwhile, to commemorate the conclusion of their royal tour, the King and Queen of England published a stunning portrait on Saturday, which elicited a significant response from the audience.

This shot was taken by Chris Jackson, a royal photographer for Getty. It depicts Charles and Camilla on a beach in Apia, Samoa.

The Queen's husband wears a beige suit, grins at her with adoration, and wears a white tunic dress with blue embroidery. The 77-year-old Queen appears exquisite in her clothing.

"As our visits to Australia and Samoa come to a close, my wife and I would like to thank both nations for the warmest of welcomes and for the countless fond memories we will carry in our hearts for many years to come. Even when we are far apart in distance, the many close connections that unite us across the globe and through our Commonwealth family have been renewed, and will remain as profound as they are enduring," their personal message read.

An official from the palace said that the King "genuinely loved" the visit and "genuinely thrived" on the Australian and Samoan program. The official also stated that the trip improved "his spirits, his mood, and his recovery."

"In that sense, the tour, despite its demands, has been the perfect tonic".

He went on to explain that the Queen's presence was a source of immense strength for the king, not the least of which was the fact that she "keeps it real."

The cancer treatment that Charles was receiving was temporarily put on hold while he was on the long-distance trip; nevertheless, it has been verified that other trips abroad are scheduled for the following year as he continues to manage the disease.

It is generally accepted that the King will travel overseas between the spring and autumn seasons, which are the usual times for official royal journeys abroad, provided the king's physicians give their approval for the trip.

Since the beginning of February, the monarch has been getting treatment as an out-patient for an unidentified form of cancer. Initially, he delayed all duties requiring him to interact with the public and continued to work behind the scenes. However, he became available to participate in events with the general public in late April.

Despite being accosted by Senator Lidia Thorpe in Parliament House in Canberra, the trip was overall a nice experience, and King Charles was "unruffled" by the outburst, as per HELLO Magazine.

Some of the highlights in Australia were the royal couple attending a community BBQ and greeting hundreds of people in front of the Sydney Opera House. Additionally, in Samoa, they were welcomed with open arms at several tea ceremonies.
