Kuwait's crown prince steps in following emir's hospitalisation
"The crown prince [Sheikh Nawaf al-Ahmad Al-Sabah] is to temporarily execute certain prerogatives of the emir," his half-brother, the head of state's office announced, quoted by KUNA.
The agency reported earlier that Sheikh Sabah, ruler of the oil-rich Gulf state since 2006, was hospitalised "to undergo medical tests".
In September 2019, Sheikh Sabah underwent medical tests shortly after arriving in the United States, leading to a meeting with President Donald Trump being called off.
The emir had his appendix removed in 2002, two years after having a pacemaker implanted. In 2007, he underwent urinary tract surgery in the United States.
Sheikh Sabah argued last year for de-escalation in the Gulf as tensions surged between the US and its arch-foe Iran.
