(I am going to add this, here, and make it my thread of Royal Styles and Titles.)
PART 1
I suspect King Charles has pulled a fast one.
More precisely, I think he may have killed two birds with one carefully crafted stone in his act to remove Andrew's HRH and princely title. (See below.)
I would argue two points:
1. KC did NOT remove Andrew's HRH and princely title.
2. KC DID make his wish known that the Invisikids have NO "entitlement" to the style 'Royal Highness' nor the titular dignity of Prince or Princess, under the 1917 LP.
I'll start with #2.
Within KC's LP, he removed "THE ENTITLEMENT" (noun) that he states entitled Andrew to the style 'HRH' and the titular dignity of 'Prince'. (Compare with the LP removing "THE ENTITLEMENT" to HRH for ex-wives below.)
He sets out by referencing the 1917 LP. Specifically, KC refers to the section regarding the children of the monarch, and ALSO the children of the sons of the monarch.
While I disagree that the 1917 LP entitles the aforementioned to the titular dignity of Prince or Princess, a plain reading of KC's proclamation states "the above-mentioned ENTITLEMENT" is removed.
Such "entitlement," however, is not specific to one individual.
By his direct reference, any "entitlement" applies to the children of the monarch & ALSO the children of the sons of the monarch. Regardless, it is removed.
I believe this was the true goal of his LP, while not drawing attention to it.
KC goes on to say that Andrew is specifically no longer "entitled" (verb), under the last section & I'll get to that in the next part.
And, of course, The Wales children are entitled to their styles & titular dignities, under QEII's 2012 LP.
