Riyadh: Kuwait’s Crown Prince Shaikh Nawaf Al Ahmad Al Sabah left the United States following medical tests on Friday, state news agency KUNA reported.
The crown prince went to New York for “routine” medical check-ups 10 days ago, KUNA reported.
He also went to the United States for medical check-ups last August.
Shaikh Nawaf, 80-year-old brother of Kuwait’s ruler, underwent minor back surgery in 2013 in Germany.
A relatively low-profile figure, he became next in line to lead the US-allied oil exporter in 2006, shortly after Shaikh Sabah Al Ahmad Al Sabah became ruling emir.
The health of leading members of the ruling family is a sensitive issue in Kuwait, where less senior Al Sabah members have long been jostling for position, according to diplomats and analysts.
It is not public knowledge who is third in line in Kuwait, an OPEC member state.
