Djibouti's president, Guelleh, succeeded Hassan Gouled Aptidon in office in 1999. Guelleh was sworn in for his second six-year term after a one-man election on 8 April 2005. He took 100% of the votes in a 78.9% turnout. In early 2011, the Djiboutian citizenry took part in a series of protests against the long-serving government, which were associated with the larger Arab Spring demonstrations. Guelleh was re-elected to a third term later that year, with 80.63% of the vote in a 75% turnout. Although opposition groups boycotted the ballot over changes to the constitution permitting Guelleh to run again for office, international observers from the African Union generally described the election as free and fair.
