Kuwait's official news agency says the Cabinet has resigned ahead a reshuffle and plans by some legislators to submit a number of ministers to parliamentary grilling.

KUNA quoted parliament speaker Marzouk al-Ghanem as saying Monday he had received a letter that all 16 ministers submitted their resignations.

The Cabinet, which included seven members of the ruling al-Sabah family, was formed in August after parliamentary elections in July. Those elections were called after a constitutional court threw out the results of a December 2012 poll.

For decades, Kuwait has allowed the most politically vibrant culture in the Gulf. Opposition lawmakers have a powerful forum in parliament, often summoning officials to be questioned on policies. It has been dissolved in the past however when friction with the government became too high.
