will Meghan Markle make a great queen or the best queen?

Neither. Meghan will never be queen consort as her husband will never be king.

Meghan can strive to become a good role model, a tireless worker for various foundations, charities and military appointments.

No. Hopefully the monarch will be abolished anyway before her time comes.

She will not make any short of Queen, To many in front of her.

I think you already know the answer troll.

Unless something really devastating happens to the six in front of him, in the line of succession, She will never be Queen.

She will never be Queen, her step mother in law and her husbands sister in law are going to be the next two queens

she will never be queen so its immaterial to ask

There are currently six people who are in line to succeed to the British throne before the Duchess of Sussex's husband.

So she will almost certainly never become Queen.

a good queen

If and that’s a BIG if she gets to be queen, I’m sure she’ll do the best job she can.
