Elections in Egypt are held for the President and a bicameral legislature. The President of Egypt is elected for a six-year term by popular vote after draft amendments to the 2013 constitution altered the presidential term limits from the original four years to six years. Suffrage is universal and compulsory for every Egyptian citizen over 18. Failure to vote can result in a fine or even imprisonment, but in practice, a significant percentage of eligible voters do not vote. About 63 million voters are registered to vote out of a population of more than 100 million. Turnout in the 2011 parliamentary election was 54%. The Kingdom of Egypt was granted nominal independence by the United Kingdom on 28 February 1922. Between the Declaration of 1922 and the Revolution of 1952, ten general elections were held (in 1924, 1925, 1926, 1929, 1931, 1936, 1938, 1942, 1945 and 1950). This era is generally known as Egypt's Liberal Experiment. Egypt has never recovered the level of political freedom it enjoyed during this period. During the four elections held between 1924 and 1929, candidates from the Coptic Christian minority received 15 to 23 seats. Copts received four seats in 1931, six in 1938, 12 in 1945, and five in 1950. The opposition's share of seats also varied throughout this period. The opposition won 15.1% of the seats in the 1924 election, 18.9% in 1926, 6.9% in 1929, 18.1% in 1936, 12.1% in 1942, and 29.2% in the 1950 election, the last to be held before the 1952 Revolution which ended Egypt's multi-party system. 2005 Egyptian presidential election Under the Mubarak era, the Egyptian presidential election of 2005 was the first-ever multi-party, multi-candidate contested presidential election in Egypt's history, made under the 2005/2007 constitutional amendments to the 1971 Constitution of Egypt. Despite its significance, the election was marred by voter fraud, ballot stuffing, boycotts, intimidation, vote-buying, and protests by opposition groups, leading to a low turnout of under 30%.
