Prince Philip promised his Duke of Edinburgh title to Prince Edward, but it's reportedly going to Prince Charles

Prince Philip's title of Duke of Edinburgh could bypass Prince Edward and go to Prince Charles, according to royal experts.

After Philip's death on Friday, speculation began over who would inherit the title. Edward had been set to take on the title and its responsibilities, but Charles could add the title to his long list of accolades before his younger brother.

In 1999, when Edward married Sophie Rhys-Jones, Buckingham Palace said he would be given the title "in due course, when the present title now held by Prince Philip eventually reverts to the Crown."

Currently Edward holds only the title of Earl of Wessex, while Charles is known as the Prince of Wales, as well as the Duke of Rothesay when he is in Scotland and the Duke of Cornwall when he is visiting the South West of England.

Lizzie Robinson, a host of ITV's "Royal Rota" podcast, told listeners in an episode released on Monday that the title "will pass to Prince Edward eventually, but right now it's passed to Prince Charles."

"When Prince Charles becomes king, the title returns back to the Crown. It's at that point that it can be given to Prince Edward," she explained.

Robinson's cohost, Chris Ship, ITV News' royal editor, said that "it passes to Prince Charles because he is the eldest son, but he won't use it because he's got his other titles."

"Obviously Prince of Wales, heir to the throne, Duke of Rothesay, Duke of Cornwall and all the rest of it," he added. "So it will be Prince Edward who will be the future Duke of Edinburgh. He will now, therefore, take over and steer the Duke of Edinburgh's Award scheme."

The youth awards program in the United Kingdom founded by Philip in 1956 encourages young people to build "essential skills, experience, confidence and resilience," its website says.

As CBS News reported, the title was initially given to Prince Frederick by his grandfather, King George I, in 1726. Philip was awarded the title when he gave up his status as the prince of Greece and Denmark to be able to marry Queen Elizabeth II in 1947.

The CBS report also noted that when Charles becomes king, the title will "merge with the crown," and he will be able to bestow it upon Edward. His wife, Sophie, Countess of Wessex, will become the Duchess of Edinburgh, a title the Queen held until she ascended the throne.
