The relationship between Kate Middleton and Meghan Markle has always been the subject of great analysis and public scrutiny. It has been rumored that the relationship has always been tense and that the reason lies in the rivalry between the two. Now, Buckingham has seen how these theories gain strength after the big argument between Kate and Meghan at the Palace came to light.
In May 2018, during the preparations for the royal wedding between Prince Harry and Meghan Markle, a conflict arose between Meghan and Kate. The reason was Princess Charlotte's bridesmaid dress. In that argument, terrible things were said that made both cry, not just the actress, as was reported at the time.

The big argument between Kate Middleton and Meghan Markle comes to light
That Kate Middleton and Meghan Markle don't get along particularly well is something the international press has always addressed. Especially after the Duke and Duchess of Sussex cut all ties with the British Royal Family and lashed out against it.
Thanks to the book Yes, Ma’am: The Secret Life of Royal Servants, one of the most murky episodes of both has just come to light. In Buckingham, there is great concern seeing how the worst side of Middleton and Meghan has become public. To understand it, we have to go back to 2018 when Markle was in the middle of preparations for her wedding with Prince Harry.

During these, Kate showed her discomfort with the dress her daughter Charlotte would wear for such a significant day. This triggered a series of unfortunate comments from Kate and Meghan that ended up causing tears in both.
Meghan Markle, in an interview with Oprah Winfrey in 2021, stated that she was the one who cried after the argument, and that Kate apologized afterward. She said nothing at that time about Middleton also being very upset by the words her sister-in-law said during the confrontation. It is now known that Prince William's wife also ended up crying, and it is unknown if Meghan apologized to her as Kate did.
The origin of the conflict between Kate Middleton and Meghan Markle
Princess Charlotte's dress was only the trigger for a tension that had existed for some time between Kate and Meghan. While it was a moment of maximum tension between them, it was the confirmation of their bad relationship.
In the midst of this controversy, Markle's brother came on the scene, claiming in an interview that Meghan felt jealous of Kate. The relationship between Meghan and Kate has been marked by tensions and constant comparisons. Since her arrival in the royal family, Meghan has felt that her sister-in-law receives preferential treatment from the institution and the media.

According to some experts, these perceptions have fueled feelings of jealousy and frustration in the Duchess of Sussex. In fact, in interviews, she has pointed out that if Kate were the subject of similar criticism, the Royal Family wouldn't tolerate it and would come to her defense.
Meghan also expressed feeling overshadowed by Kate's popularity, especially at public events where media attention focused on the Princess of Wales. All of this created a breeding ground that ended up exploding in an unprecedented argument.
To this day, the contact between them is nonexistent, and there is a firm predisposition to keep their distance. It is evident that there are more than enough reasons between Kate and Meghan not to make peace and for each to follow different paths.
