Sheikh Meshaal Al-Ahmad Al-Jaber Al-Sabah took the constitutional oath on Thursday before the National Assembly as the crown prince of Kuwait.
Kuwait's parliament unanimously voted earlier on Thursday to endorse the veteran security chief as crown prince after the new emir named him on Wednesday, the parliament said on Twitter.
Sheikh Nawaf Al-Sabah assumed power as emir following the death of his brother Sheikh Sabah Al-Ahmad last week.
Sheikh Meshal, a brother of the late emir, became deputy head of the National Guard in 2004 and previously served as head of State Security for 13 years.
Kuwait is due to hold a parliamentary election this year.
