Opposition Islamist lawmakers have walked out of Egypt's parliament to protest against the expulsion of a fellow MP who had criticised the government for letting a French warship through the Suez Canal. The Muslim Brotherhood said on its web site that parliament speaker Fathi Sorour had expelled Mustafa Mohamed Mustafa on Saturday "to deny the Muslim Brotherhood MPs the chance to reveal new scandals of the Egyptian government in the matter of the French ship Clemenceau". The Clemenceau is a 27,000-tonne aircraft carrier which is heading to India to be scrapped. Environment group Greenpeace says the ship contains hundreds of tonnes of hazardous materials, including 500 tonnes of asbestos. The government this week allowed the Clemenceau through the Suez Canal en route to India and said the ship did not pose an environmental threat.
