Eritrea is a unitary one-party presidential republic in which national legislative and presidential elections have never been held. Isaias Afwerki has served as president since its official independence in 1993. According to Human Rights Watch, the Eritrean government's human rights record is among the worst in the world. The Eritrean government has dismissed these allegations as politically motivated. Freedom of the press in Eritrea is extremely limited, the Press Freedom Index consistently ranks it as one of the least free countries. As of 2021 Reporters Without Borders considers the country to have the overall worst press freedom in the world as all media publications and access are heavily controlled by the government.
