[JURIST] The three main opposition parties [2004 IslamOnline backgrounder] in Egypt, the moderate-left Wafd [Wikipedia entry], Marxist Tagamu [Arab Decision backgrounder], and the Nasserist Party [Arab Decision backgrounder] have joined forces to voice their opposition to a May 25 referendum on an Egyptian constitutional amendment [JURIST report] allowing competitive presidential polls. They charge that the conditions for registration are so stringent that only the ruling National Democratic Party [official website, English version] would be able to field a candidate, undercutting the purpose of the referendum. The opposition parties along with the outlawed Muslim Brotherhood [party website in Arabic] have urged Egyptian voters to avoid the polls on May 25 in protest. AFP has more.
