								Mixed system: - 31 members are elected using the first-past-the-post (FPTP) system;
 - 209 members are elected under the proportional representation (PR) system using the closed party list. These seats are distributed according to the Hare-Niemeyer method.
 Only parties and coalitions that obtain at least 4 per cent of the nationwide popular vote are entitled to parliamentary representation.
 Vacancies for the PR seats are filled by "next-in-line" candidates. Vacant FPTP seats are filled through by-elections. However, if a member elected under the FPTP resigns to take up a ministerial post, his/her seat will be filled by the "next-in-line" candidate of the same party from the proportional representation system.
 Voting is not compulsory.
