The Crown announce the Pregnancy of William and Catherine

[Tyburn]

They wanted to keep it a secret until Christmas...but couldnt when Catherine got such bad morning sickness they had to take her to hospital

Prince William, and the Duchess of Cambridge are expecting their first Child

The Rules and regulations for the new line of succession states that from the Birth of the reigning Monarchs Great-Grandchildren, the order of Succession will pass in chronology of Birth, no matter what Gender is born and in what order.

Therefore if William and Catherine have two children, the Oldest Female, the Youngest Male...it is the Female and NOT the Male who will rule first

The Birth of this Child will subsequently remove, most probably, Prince Harry from the running order, as William AND his Children will all have to rule first. The Child will instanteniously be the Third in Line, following His Father, and his GrandFather...and of course His Great Grand Mother who is regnant now.

To Remind you...this was when they got Married

This is of course her main Royal Duty...for She can NEVER rule. Though she will be bestowed with the Title of Queen, most probably...she is what is known as "Queen Dowager" NOT "Queen Regnant" in theory we have a King right now...The Duke...He is King Dowager.

If they feel its inappropriate they can use a number of terms...for example, they could call Catherine, in future, The Kings Consort

But there has only ever been ONE time where BOTH Male and Female Married Monarchs were both Regnant and Soverign...and that was Queen Mary, and King William. They were Co-Regnant during the time of The Glorious Revolution.

Therefore, he main Royal Duty is NOT to lead...but to Produce the continuation of the Royal Line. What she has to do is Breed, successfully, and where possible produce Male offspring and they like to start as soon as possible, because obviously these Babies have to grow up before they can reign in their own right...so you get married, and then have lots of children...and hope they are nice and ripe in age before they inherit the throne. This ensures not only the Monarchic Future, and the line, but more importantly, it provides a future for the Ruling Dynastic House.

In past times, failure of the women on this level has meant that, if they are monarchs their houses are doomed to die with them, just like what happened when Elizabeth 1st died...and if they are not Regnant...well..usually they got discarded at best...murdered at worst.
