However, this is not relevant to King Charles at present, who continues to serve as Supreme Governor of the Church of England.
What Would Happen to Queen Camilla?

If King Charles were to step down or pass away, Queen Camilla would retain the title of Queen Consort, but her role would naturally diminish. Since her title is tied to her marriage to the monarch, it does not grant sovereign authority.
When Prince William becomes king, Kate would take over as Queen Consort. Camilla might continue to appear at some official events but would likely withdraw from frontline royal duties over time.
Are There Real Reports That Charles Is Considering It?

Royal commentator Clive Irving, author of The Last Queen, recently claimed that King Charles may have discussed plans to abdicate around the age of 80. According to Irving, the King might wish to oversee a few key years of transition — smoothing over relations within the monarchy, particularly concerning Prince Harry — before handing the crown to Prince William.
No formal timeline has been shared, and these reports remain speculative. The palace has not confirmed or denied any plans for early retirement.
Final Thoughts

While King Charles has shown commitment to serving “for the remainder of the time God grants” him — echoing his mother’s lifelong dedication — the idea of abdication is not entirely off the table in modern monarchies.
For now, though, Britain’s king remains on the throne, with Prince William continuing to support his father as heir apparent. The monarchy may evolve in the years ahead, but any transition will likely be measured, constitutional, and carefully choreographed.
