It is always good to plan for the future, even more so when something is inevitable. Nonetheless, there seems to be so much about “when Charles is King” and then moving forward with those plans. Is there something about the Queen which hasn’t been announced yet?
Charles does seem to be “measuring the drapes”.
You don’t think heads of state and governments think and plan into the future?
(Last time I saw her out-and-about, she looked fine.)
