Prince Charles is the eldest son of Queen Elizabeth and Prince Philip. Once Her Majesty decided to retire, or there will be some circumstances that she couldn’t lead the monarchy anymore, the Prince of Wales will serve as King as he is the heir apparent to the British throne.

While this royal tradition has been followed for centuries, Prince Charles is reportedly making Queen Elizabeth and Prince Philip worry if he is fit to be King. A royal biographer claimed that the Prince of Wales made his parents believe that they “could not trust him” because he tends to be outspoken.

"He annoyed his parents, actually,” Angela Levin said in the documentary The Queen and Prince Charles: Mother and Son. "They felt he was weak, they felt they couldn’t trust him to be king, that he had all these funny ideas about spiritualism and plastic in the sea."

Royal historian Dr. Kate Williams noted that Prince Charles has sparked criticism from the public for his outspokenness. The Royal Family is expected to remain neutral on most matters, but the future King is not afraid to share his personal opinions.

"Increasingly, people started talking about Prince Charles as a bit eccentric,” she said. "There are cartoons of him talking to his plants, and thinking too much about his plants."

Prince Charles is known for his deep-rooted love of the environment. The future king would share updates about environmental issues to spread awareness about the matter.

In fact, Prince Charles pleaded that everyone should learn their lessons and change their behaviors once the coronavirus pandemic ends. He urged Britons and people all around the world not to return to their old ways of living. Instead, everyone should understand the “crucial importance of Nature.”

"At the same time, I sense that more people, be they in cities or the countryside, are noticing and appreciating Nature in a way they had not before — they are alive to the beauty of the wildflowers and the first glorious delicate green as the trees start to unfurl their leaves; of birdsong and the wonderful array of butterflies and bees that are suddenly bursting into hyperactivity,” he wrote. ”When we come out of this pandemic, as we surely will, it seems to me that we must learn some lessons: of the crucial importance of Nature to our wellbeing and to our very existence; of the power of localization; and simply of a kinder way of being. After the suffering and the selflessness we are witnessing, we cannot allow ourselves to go back to how we were. This is a moment in history."
