Thread: How is the civil union (i.e. gay marriage) treated in the UK rules of succession?

I was wondering that since UK is amongst the first countries that accepted gay marriage, if that applies also to their royal family. Let's say that one member in line to the throne comes out and marries his or her partner. Does he/she lose his/her place to the succession line? Does the partner has the same rights and titles as any other royal consort?

Just for example, say that HRH The Prince Alexander (a fictional son of Queen Elizabeth II, born after Prince Edward), was openly gay and was to marry his long-time lover Mr. James Tudor. Then:

a) Legally, he would keep his place to the succession line (i.e. 10th)?

b) What would be the proper title and style of Mr. Tudor? To stretch it even more, what would Mr. Tudor called in the occasion that the fictional Prince Alexander becomes King Alexander IV of the UK? Would Alexander have the right to grand to his partner a "Prince Consort" status, or given him a title, in the same manner the current Queen names her children Dukes on their wedding day?
Paco your answer implies that Alexander would be treated as unmarried in the succession rules after his civil union and Mr. Tudor would be nobody for the royal family.

What about the first part of the question, would he still be in the succession line?
BSRT serious answers only, please...

there are no laws to remove homosexuals from secession

no it is a civil union not a marriage, there are no rights accrued by a spouse everything is derived through the blood secession, titles and everything else is at the discretion of monarch

They ,who ever,would NOT be married in the eyes of the Church,therefore would NOT be eligible to ascend the Throne.
Gays go through a civil partnership ceremony,NOT a marriage,lets get that straight,excuse the pun !

Both of them will be styled and called Their Majesties the Queers.

Civil rules have no effect on laws governing royals or peerages. Similarly in the UK you can be "legitimated by marriage" or if you are born to parents who get married after your birth, then you are legitimate. However, with regard to the line of succession you are forever banned.
