Opposition lawmakers are seeking to question a senior government official over alleged misuse of public funds in housing deals and other projects.
Tuesday's formal request to question deputy prime minister for economic affairs, Sheik Ahmad Al Fahad Al Sabah, is the latest push by Kuwait's anti-government bloc to draw attention to accusations of political abuses by the government and the ruling family.
Kuwait has the Gulf's most powerful parliament. It has twice brought no-confidence motions against the prime minister, who survived both times.
The latest accusations claim Sheik Ahmad mishandled public funds in contracts for housing and sporting events.
The questioning is expected on April 5.
