The emirate was plunged into a new round of political disputes a day earlier when three lawmakers filed to quiz the prime minister, raising the possibility of parliament being dissolved for the third time in as many years.
Waleed al-Tabtabai, Abdullah al-Barghash and Mohammed Hayef, all Sunni Muslim Salafists, called for the debate, which will take place in two weeks.
They have accused Prime Minister Sheikh Nasser Mohammed al-Ahmad al-Sabah, a nephew of the emir, of allowing a prominent Iranian Shiite cleric to enter Kuwait despite a legal ban.
They have also accused him of failing to "perform his constitutional duties … and that it was time that Kuwait had a premier capable of running the state and achieving the wishes of the people."
And they have alleged that corruption and squandering of public funds had rapidly increased under the leadership of Sheikh Nasser, who is a senior member of the ruling family.
On Wednesday, the government and MPs were busy searching for a way out of the new crisis.
As Tabtabai kept up pressure, all options were on the table including dissolving or suspending parliament and the constitution.
"The Kuwaiti people deserve a better government," he said in a statement.
But Shiite MP Ahmad Lari said a majority of lawmakers are against the grilling and that there is no cause for high tension.
Islamist MP Khaled Sultan told reporters that "dissolving or suspending parliament is not in the interest of Kuwait at this stage," adding that the grilling request could be sent to the constitutional court to decide on.
Independent Islamist MP Adel al-Saraawi has said crises will continue to hit the oil-rich emirate as long as the Al-Sabah disputes remained unresolved.
"The key to resolving crises in the country is through settling disputes among some members of the ruling family … which have a direct and essential impact on the country’s political dilemma," Saraawi said.
"The prime minister has no dispute with parliament. His real dispute is with some members of the ruling family," the lawmaker said in a statement published by local newspapers.
Leading Shiite MP Hussein al-Qallaf suggested that these disputes were behind the latest parliamentary move.
"This is a grilling by proxy and is a reflection of the dispute within the ruling family … Some (MPs) have made themselves available as tools for ruling family members," he said in a statement.
Independent MP Nasser al-Duwailah criticised some of his colleagues "who are being used by members of the ruling family to create tension."
He charged that the aim of some ruling family members is to "end democracy and abolish the constitution, and this group constitutes a danger to the political system."
Kuwait’s constitution, the first adopted by an Arab state in the Gulf, was suspended in 1976 for five years and in 1986 for six years when parliament was also dissolved.
In 2006, a power struggle among the Al-Sabahs resulted in an unprecedented vote by the elected parliament to remove the emir, Sheikh Saad Abdullah al-Sabah, on health grounds.
The family has run the affairs of Kuwait since it came into existence some 250 years ago, and Kuwaitis have seldom questioned their continuing rule.
The emir, crown prince and the prime minister are all from the family, which also controls the key ministerial portfolios of defence, interior, information and foreign affairs.
