Saudi crown prince returns home after medical tests

LONDON - Crown Prince Nayef has returned to Saudi Arabia, a month after traveling to the United States for medical tests, the state news agency said early on Wednesday.
Prince Nayef, who is about 78, went to Cleveland in March for "scheduled medical tests," Saudi state television said at the time.
Because the Saudi system of government centralizes a great deal of power at the very top, the health, views and prospects of senior princes are closely scrutinized.
