Constitutional experts warned that Kate giving birth to twins could be storing up a war between the Windsor's over the coming fifty years.
Nick Clegg promised to get new legislation through enabling Kate's first daughter, were she to give birth to one, to be Queen, like her brother would become King if her baby was a boy.
But if there are twins it all depends on which one comes out first, a constitutional timing expert pointed out.
Worries are growing that if it is a multiple birth, and the boy comes out second but legislation hasn't been passed by the time of the birth, then it could open up an enormous row if the boy wants to take the throne, like his sister, sometime in the future.
It could be even worse if Kate gives birth to triplets and the girl is first and two boys are second and third.
It could be even worse than that if it's quadruplets and the girl is first and the boy is second and a girl is third and the boy is fourth.
Nick Clegg was unavailable for a clarification when we put this to him last night.
