For the first time since Spain re-adopted democracy in the 1970s, a member of its royal family has been summoned for testimony as a criminal suspect. Princess Cristina, King Juan Carlos' youngest daughter, is suspected in a case related to her husband's financial dealings. Iñaki Urdangarin allegedly moved public funds for a nonprofit group to his own for-profit firms, the Wall Street Journal reports. The princess was on the nonprofit's board. Her husband is also facing a tax evasion probe. His lawyer denies wrongdoing, and neither has been charged.
