Egypt:

Constitutional changes voted on 19 March 2007 prohibited parties from using religion as a basis for political activity, allowed the drafting of a new anti-terrorism law, authorised broad police powers of arrest and surveillance, and gave the president power to dissolve parliament and end judicial election monitoring. In 2009, Dr. Ali El Deen Hilal Dessouki, Media Secretary of the National Democratic Party (NDP), described Egypt as a "pharaonic" political system, and democracy as a "long-term goal". Dessouki also stated that "the real center of power in Egypt is the military".
