The BBC website has an article. An excerpt:
Juan Carlos, 76, signed the bill at a ceremony in the Royal Palace in Madrid, which was attended by only 160 guests.There will be no coronation, however, for Prince Felipe:At midnight local time (22:00 GMT), Felipe, 46, will become king although the event will not be marked in public until Thursday morning.
The succession was endorsed by both of Spain's main political parties.
Before the signing, Juan Carlos sat with Queen Sofia to his right and Prince Felipe and Princess Letizia to his left as the content of the law was read out.
The ceremony at 10:30 local time will take the form of a proclamation rather than a coronation, in part because of the economic hardship that many Spaniards have experienced in recent years.I've got my issues with monarchy, but this transition is important for Spain. It was contentious, especially over the idea of maintaining the monarchy, but it was peaceful. I wonder what it will look like when the Queen of England dies.
