KUWAIT CITY (AFP) – Kuwaiti opposition MPs stormed out of parliament on Tuesday to protest a decision to grill the prime minister behind closed doors over alleged inaction on pollution.

Four opposition MPs – including Khaled al-Tahus who had called for a public debate – walked out after 39 lawmakers voted to hold a secret session to quiz the premier, speaker Jassem Al Khorafi said.

Khorafi said he decided to cancel the session altogether as a result.

Tahus last month demanded to question Prime Minister Sheikh Nasser Mohammad Al Ahmad Al Sabah, a nephew of the ruler, over allegations that he failed to apply the law to check pollution in a residential area.

MP Mussallam Al Barrak told reporters that the deputies withdrew from the session because of the decision to hide important information from the Kuwaiti people.

“Our demand is to have an open discussion in the parliament chamber” to allow the Kuwaiti people to hear the truth, Barrak said. “All we want is for the residents in that area to breathe clean air.”

He announced that the Popular Action Bloc group headed by veteran lawmaker Ahmad Al Saadun will demand to grill the premier once again over the same issue, but he did not give a date.
