of Cambridge, "were to have a little girl [as their first
child], that girl would one day be our queen," British Prime
Minister David Cameron said Friday.  The leaders of the
Commonwealth's 16 realms — the countries that have the Queen as
their head of state among the 54 total members of
the Commonwealth — unanimously agreed to the succession change
at their meeting in Perth, Australia.  The leaders also agreed
to lift a ban on the monarch being married to a Roman Catholic.
"Attitudes have changed fundamentally over the centuries and
some of the outdated rules — like some of the rules of
succession — just don't make sense to us anymore," Cameron said.
