Estonia country profile
President: Toomas Hendrik Ilves
Mr Ilves was first sworn in as president in October 2006.
As head of state, the president is supreme commander of the armed forces and represents Estonia abroad. However, the role is mainly ceremonial.
The president is elected to a five-year term by MPs and local officials. Mr Ilves was re-elected for a second five-year term in August 2011.
Born in 1953, Mr Ilves is a member of the centre-left Social Democratic Party.
Prime minister: Taavi Roivas
Prime Minister Taavi Roivas became the European Union's youngest head of government in March 2014.
He was designated prime minister by President Toomas Hendrik Ilves when his predecessor Andrus Ansip stepped down after a record nine years in office.
Mr Ansip's popularity had flagged of late, and his resignation was designed to bring in fresh blood ahead of the centre-right party's run for re-election in 2015.
Mr Roivas, aged 34 at the time of taking office, heads a coalition consisting of his centre-right Reform Party and the center-left Social Democratic Party.
His coalition commands a wafer-thin majority of just 52 seats in the 101-member parliament.
He vowed to make security a priority as tensions ran high in Estonia and fellow Baltic states Latvia and Lithuania over moves by their Soviet-era master Russia in Ukraine.
Mr Roivas served as the minister for social affairs in the previous government.
