In the wake of a corruption case that shook the Royal Family of Spain, Iñaki Urdangarin, the husband of Princess Cristina, has been told he has five days to report to a prison to start his sentence.
He will serve five years and 10 months for embezzlement, influence-peddling and tax fraud.
The princess herself was cleared of involvement in last year's trial.
She was the first member of the royal family to go on trial in modern Spanish history.
Urdangarin will become the first royal member to go to jail.
