Prince William remains third in line to the throne after his father Prince Charles
Prince Charles has spent most of his life waiting for his mother Queen Elizabeth II to give up her throne as she currently stands as the longest-reigning monarch in British history.
And as Prince William remains third in line to the throne, one question that has hovered over the heads of many is whether or not the line of succession would face alterations in case any unforeseen circumstances are to occur in the life of the heir apparent.
As Prince Charles reaches the age of 72, government and constitution professor Robert Hazell explained in an interview with Insider what were to happen if Charles died before his mother.
"During William's lifetime, he will almost certainly see his father become King. Only if Charles dies before the Queen would William become king when the queen dies,” he said.
He further explained how the throne is passed on to the next possible heir in case someone in the line passes away.
