The Prince and Princess of Liechtenstein have sent their regrets and will not be able to attend the wedding of Prince William and Miss Catherine Middleton. The Prince and Princess have another commitment, the beatification ceremony for the late Pope John Paul II.
Although the Princely family is very large, most members do not live in the tiny principality and carry out official duties. Official duties are carried out by the Prince and Princess and the Hereditary Prince and Princess. The Prince's two younger sons, Prince Constantin and Prince Maximilian live with their families outside the country. Prince Max is the chief executive officer of the Liechtenstein Global Trust. Tatjana, who lost her title of Princess (but not her HSH), when she married Philipp von Lattorf, lives quietly with her husband and children in Austria. She and her brothers are seen at the National Day celebrations, but do not take on any official duties.
Prince Hans Adam has two younger brothers. Prince Philippe has lived in France for many years with his wife, Isabelle, and their family, Prince Nikolaus, who recently retired as Liechtenstein's ambassador to Belgium, and his wife, Princess Margaretha of Luxembourg, have moved back to Liechtenstein, but neither carry out official duties.
The King and Queen of Jordan are not on the list of foreign royals. It was said that they had confirmed, but perhaps due to the rising tensions in the country, the King and Queen have decided to forgo the wedding.
