A constitutional referendum was held in Egypt on 19 March 2011, following the 2011 Egyptian revolution. More than 14 million (77%) were in favour, while around 4 million (23%) opposed the changes; 41% of 45 million eligible voters turned out to vote.
The approved constitutional reforms included a limitation on the presidency to at most two four-year terms, judicial supervision of elections, a requirement for the president to appoint at least one vice president, a commission to draft a new constitution following the parliamentary election, and easier access to presidential elections by candidates—via 30,000 signatures from at least 15 provinces, 30 members of a chamber of the legislature, or nomination by a party holding at least one seat in the legislature.
The reforms were recognised by both sides to increase democratic safeguards, but opponents argued that they did not go far enough and that an election held too soon could favour the well-organised Muslim Brotherhood and members of the former ruling National Democratic Party of Hosni Mubarak. Supporters cited concerns that waiting too long could increase the chances of the military regaining power or risk destabilisation before an election.
A parliamentary election is planned within the next six months, with groups already working to create new political parties, promote candidates and increase turnout among their supporters.
Had the referendum resulted in a "no" vote, the 1971 constitution would have been nullified and a new one was to be drawn up before elections, which would likely have extended the planned transition period until an election to 2012.
