KUWAIT (Reuters) - Kuwaiti opposition lawmakers filed a motion of non-cooperation against the prime minister on Tuesday, a step that may prompt the ruler of the OPEC member to reshuffle the cabinet or dissolve parliament. The motion, which is to be voted on in a session on Jan. 5, has to be passed by a majority in parliament before being sent to the emir. The move came hours after the house questioned Prime Minister Sheikh Nasser al-Mohammad al-Sabah, a nephew of the emir, in a closed session over alleged violations of the constitution and public freedom. Earlier this month, three lawmakers had submitted a request to question him about an incident in which police broke up an opposition gathering, wounding several people. Kuwait's parliament, the most outspoken in a region mostly governed by ruling families, has triggered numerous cabinet resignations or reshuffles. Frequent government reshuffles, resignations and parliament dissolutions have in the past delayed economic reform bills. The cabinet had to pass a $5 billion stimulus package as a by-law last year while parliament was dissolved. Under the constitution, each member of parliament has the right to question government ministers. Last year Sheikh Nasser agreed to be questioned by parliament, which was a first for a head of government in the Gulf state. He survived a similar non-cooperation motion.
