The pro-reform MPs left Monday's session when voting began on a motion tabled by conservative and tribal MPs that sought to refer a government-backed bill reducing the number of constituencies from 25 to 10 to the constitutional court.

Twenty-eight of parliament's 50 MPs walked out when a government minister became the first to vote in favour of the motion.

Chants of "Down with the government," "Long live Kuwait," and "We want five (constituencies)," came from a packed gallery as the MPs mounted the unprecedented walkout.

The reformist MPs want to go further than the government bill and slash the number of constituencies to five in a bid to fight vote-buying and other irregularities they say marred Kuwait's last general elections in 2003.

Resignation calls

Government members and their supporters in parliament left after the opposition walkout, prompting the reformist MPs to return and demand the resignation of the cabinet.

Hassan Jawhar said "the Kuwaiti people have stated clearly today that this government is not credible. It had better go."
 
"This government has effectively fallen and it should not stay one day longer," echoed liberal MP Ali al-Rashed.

Jassem al-Khorafi, the parliament speaker, said the session would resume on Tuesday to vote on the motion to refer the government bill to the constitutional court but the public would be excluded.

Asked by reporters if Monday's stormy session might lead to the  dissolution of parliament, Khorafi said this was up to Sheikh Sabah al-Ahmad al-Sabah, the emir.
