Government and politics

Sierra Leone is a constitutional republic with a directly elected president and a unicameral legislature. The current system of the Government of Sierra Leone is based on the 1991 Sierra Leone Constitution. Sierra Leone has a dominant unitary central government and a weak local government. The executive branch of the Government of Sierra Leone, headed by the president of Sierra Leone has extensive powers and influence. The president is the most powerful government official in Sierra Leone.

The president is the head of state, the head of government, and the commander-in-chief of the Sierra Leone Armed Forces. The president appoints and heads a cabinet of ministers, which must be approved by the Parliament. The president is elected by popular vote to a maximum of two five-year terms. The president is the highest and most influential position within the government of Sierra Leone.

To be elected president of Sierra Leone, a candidate must gain at least 55% of the vote. If no candidate gets 55%, there is a second-round runoff between the top two candidates.

The current president of Sierra Leone is former military junta leader Julius Maada Bio. Bio defeated Samura Kamara of the ruling All People's Congress (APC) in the country's tightly contested 2018 presidential election. Bio replaced outgoing President Ernest Bai Koroma after Bio was sworn into office on 4 April 2018 by Chief Justice Abdulai Cham. Bio is the leader of the Sierra Leone People's Party, the current ruling party in Sierra Leone.

Next to the president is the vice-president, who is the second highest-ranking government official in the executive branch of the Sierra Leone Government. As designated by the Sierra Leone Constitution, the vice-president is to become the new president of Sierra Leone upon the death, resignation, or removal of the President.
