As the longest-waiting heir apparent, commentators believe King Charles III is about to make changes in the monarchy. The new king may rule the United Kingdom differently, and it may not be like how his mother, the late Queen Elizabeth II, worked.

There are claims King Charles is now "itching to make changes" after waiting almost all his life to be the next leader of the realm. So, what will be the alterations the public is about to see?

The late Princess Diana's former husband will be crowned next year. However, with the number of issues he has to face, journalist Keir Simmons and royal commentator Daisy McAndrew revealed the "tsunami" of problems he has to deal with at the age of 73 on the podcast "Born to Rule: When Charles is King."

As the oldest person to assume the British throne, McAndrew claimed the monarch doesn't have the "goodwill" doing the job that Her Majesty used to have. At his age, most will consider retirement, but he will be in an "extraordinary position."

King Charles ascended the throne upon Queen Elizabeth's demise on September 8, signifying an end of an era. Express noted that her passing "could send ripples around the world" and even change the other countries' relationship with the monarchy.

With that said, McAndew believed further changes could happen in the kingdom as the new king might want to do things differently. "We know he's not going to just want to do it like she's done it because he's going to want to put his own mark on things," she explained.

However, the big question is will the public be ready for these changes? According to reports, he wants to amend the law that will relieve Prince Harry, Princess Beatrice, and Prince Andrew of their duties as "stand-ins for the sovereign if he is indisposed."

It is also widely believed that King Charles will have a firmer stance on Prince Andrew, ending the Duke of York's hopes to return to his public life.

Meanwhile, the upcoming coronation at ­Westminster Abbey next year is believed to embody a more modern version of the monarchy. With the ongoing crisis over the cost of living in the U.K. and many Brits worrying about their bills, Prince William and Prince Harry's father reportedly plan to reflect on these issues at the inauguration.

A royal source revealed Camilla, the Queen Consort's husband is very much aware of these problems and wants to take them into account in his celebration plans. Hence, the event will be shorter, smaller, and cheaper than Queen Elizabeth's coronation in 1953.

There are also plans to add some modern monarchy elements to the traditional ceremony and pageantry that will fit the occasion. It will include inviting an audience composed of Christian, Muslim, Jewish, Hindu, and Buddhist people.
