The royal bun in the oven

First aired on Day 6 (8/12/12)

kate-middleton-prince-william.jpgNow that Prince William and his wife, Kate, are expecting their first child, the line of succession to the throne will be changing. Day 6 invited author and European monarchy expert Leslie Carroll, whose books include Royal Romances: Titillating Tales of Passion and Power in the Palaces of Europe, to explain how the newest Windsor will fit into England's Game of Thrones.

"You can't change the laws of succession, meaning that you can't leap frog it," Carroll said. "Queen Elizabeth can't decide arbitrarily you know, 'Charles, I never really liked you very much, William is going to be the next king.' So after Queen Elizabeth, we have Charles, after Charles we have William, and if William has a baby, assuming that the law in parliament will change and that the first baby -- whichever it is, boy or girl, will inherit the throne -- baby X will then become king or queen after William."

And what if it's twins? Carroll said the future crown will rest on the head of whichever child the doctors pull out first.

Prince Harry, currently third in line for the throne, will be pushed back to fourth.
