Prime Minister Sheikh Sabah al-Khalid al-Sabah met Emir Sheikh Nawaf al-Ahmad al-Sabah, who assumed power last Wednesday, and as per the country's constitution "submitted his resignation and that of his government to ensure ministerial responsibilities are held by those who enjoy the emir's confidence", KUNA said.
It said Sheikh Nawaf expressed his full confidence in the current cabinet, which was formed last December, Reuters reported.
Sheikh Nawaf, 83, took the helm of the OPEC member state following the death of his brother Emir Sheikh Sabah al-Ahmed last Tuesday aged 91.
Kuwaitis have been waiting for Sheikh Nawaf to name a crown prince to help guide state affairs at a time when low oil prices and COVID-19 have hit state finances.
His choice must be approved by parliament.
