Security officials allowed British leftist MP George Galloway to enter Egypt on Saturday after being held 18 hours at Cairo airport, because he is on a blacklist, airport officials said. Reuters news agency reported Saturday, that the host of the British member of parliament intensified their efforts to persuade immigration authorities to allow him to enter as preparations were made in the airport for the prominent opponent of IRAQ WAR to leave Egypt, the officials added. “The Egyptian Foreign Ministry became involved in the issue and agreed Galloway could enter the country,” said an airport official who demanded anonymity. “He was refused entry on grounds of national security, presumably by the secret police,” said Ron McKay, spokesman for Galloway, an advocate of Palestinian rights.Galloway is on a visit to Cairo to participate in a mock trial of the U.S. PRESIDENT GEORGE W. BUSH , Israeli Prime Minister ARIEL SHARON and British Prime Minister TONY BLAIR for crimes they committed in IRAQ and the Palestinian territories.
