Prince William’s absence from the Windsor Castle event for King Constantine of Greece really had people talking, mainly because The Daily Mail reported that William was set to have an important role at the event. The royal was actually expected to do a reading, though the honor was instead taken over by King Constantine’s son, Crown Prince Pavlos. William wasn’t present at all because, according to Page Six, the royals had not long found out about Kate Middleton’s cancer diagnosis. In her Instagram video announcing her upsetting health issues, Kate confirmed that she had started undergoing chemotherapy in late February, which lines up with when William was expected to attend the royal event.
At the time, People confirmed that William had pulled out of the memorial due to an undisclosed reason, which was simply described back then as a “personal matter.” Though the exact reason wasn’t shared until now, it was confirmed in February that it had nothing to do with William’s dad, King Charles, who had shared his own sad cancer diagnosis a few days earlier.
