Queen Elizabeth II, 91, is said to have decided that if she is still on the throne at the age of 95 then she will request the Regency Act to come into force.

Yyyyeahhhhh. I guess the word "preparing" means something different in British than it does in English.

I would guess that it’s ‘making plans’ in the event of severe disability. I can’t see the Queen doing this if it can possibly be avoided - not because of Charles, but because of her sense of her position and her duty.

I think a lot depends on Prince Phillip. Were he to predecease her (which given that he's already 96 is likely) I think it will be very hard for her to continue without serious scale back of official duties.

Under the British system, the Regency Act is the means by which a Monarch, who is either of minor age or due to age or other infirmity is unable to discharge their duties of office, can have an official "stand in" to take over these duties. So this scenario is not unlikely.
