A source close to the situation shared with Page Six, "I have a hard time believing if his dad asks for his help that Harry would say no, I think he would try." However, the insider also noted that it is unlikely for Harry to initiate this on his own accord, stating, "I don't think it's something that Harry would ask [to do] on his own."
Another insider, speaking to The Times, emphasized the practicality of the family coming together to support the King during his illness. They explained, "On all practical levels it makes perfect sense for the family to come together to support the King while he's sick." The source further highlighted the enduring bond of blood between family members, stating that despite past conflicts, there is a recognition of the importance of considering pragmatic aspects and prioritizing the well-being of both the King and Kate.
Prince Harry's willingness to step up and assist his father reflects the deep familial ties that endure, even in challenging times. As the situation unfolds, it remains to be seen how Prince Harry's involvement in royal duties may evolve and contribute to supporting King Charles during his cancer diagnosis.
