Since ascending to the throne in 1952, Queen Elizabeth II has remained publicly neutral in terms of politics. Following her lead, the rest of the British royal family has also refrained from openly speaking about their opinions on the matter.

However, according to an "impeccable royal source," the monarch has broken her "most sacred rule" and shared her opinions, even though she knew they could eventually be made public.

According to Express via the Sunday Times, the Queen feels as though the current political class has an "inability to govern" and expressed quite a bit of disappointment in terms of how things have gone lately. These comments were reportedly made at a private event that was held after former British Prime Minister David Cameron's resignation. The insider also revealed that the royal's frustration with the events has continued to grow over time.

"I think she's really dismayed. I've heard her talking about her disappointment in the current political class and its inability to govern correctly," the source said, adding, "She expressed her exasperation and frustration about the quality of our political leadership, and that frustration will have only grown."

These comments came on the heels of claims that Prime Minister Boris Johnson would not quit if he lost a confidence vote in the House of Commons. This may cause concern for the Queen as any Prime Minister who loses a vote would be expected to resign. It is also said, according to the outlet, that refusing to do so would lead Britain "into the biggest constitutional crisis since the Civil War."

Professor Alex De Ruyter of Birmingham City University's Centre for Brexit Studies spoke about the ongoing events, saying, "It's almost impossible to see the Queen attempting to override our elected Parliament, but ignoring the request of a sitting Prime Minister is problematic for her as well."

This would not mark the first time that a royal has hinted at their political feelings, even if they have not outwardly stated them. Recently, Duchess of Sussex Meghan Markle came under fire for "politicising the royal family" and for including former First Lady Michelle Obama in the edition of British Vogue that she worked on as a guest editor.

At this time, a senior Whitehall source said that the royal household would like to "manage this in a way that doesn't change the ongoing, long-term position of the crown."
