Queen Elizabeth II may not give up the throne for her son, Prince Charles, for a number of reasons.

Reader's Digest compiled a number reasons why it's unlikely for the current monarch to step down. The publication insisted that abdication is not on Queen Elizabeth II's mind. Check out the different reasons below.

1. She promises to reign for life

Her Majesty has dedicated her life to the throne since the time she took over from her late father. She announced this on her 21st birthday.

"I declare before you all that my whole life whether it be long or short shall be devoted to your service and the service of our great imperial family to which we all belong," the Queen said.

2. She feels that it's her duty to reign

Aside from making the promise, the Queen feels that reigning is her mission in life. For this reason, she has never thought of stepping down.

"The Queen simply feels she must do her duty and she's never even contemplated abdication," Sarah Bradford said in her book "Queen Elizabeth II: Her Life in Our Times."

3. The public loves the Queen

The Queen loves the people and she has received the same affection and support from them. In fact, some don't want her to ever be replaced.

"Let [Queen Elizabeth II] reign as long as she lives. But let her be Elizabeth the Last," Polly Tonybee of The Guardian's wrote.

4. Queen doubts Prince Charles' leadership

According to Tom Bower in his book "The Power, Passion And Defiance of Prince Charles," Prince Philip and Queen Elizabeth II wanted to live longer just to keep Prince Charles from the throne. The Duke of Edinburgh was heard telling a friend that if they live longer, the Prince of Wales would "have little opportunity to damage the monarchy."

Another author also pointed out Prince Philip criticizing the heir's capacity as a leader. The Duke of Edinburgh finds his son "precious, extravagant and lacking in the dedication...to make a good king."

5. She can delegate work anyway

The Queen can keep her role and delegate more and more tasks to the younger royals including Prince William, Kate Middleton, Prince Harry and Meghan Markle. She has already practiced this. In fact, earlier this year, it was reported that the monarch has cut back on her duties. So, there's no reason for her to abdicate.
