| Notes |
In accordance with amendments to the Electoral law, promulgated on 25 July 2018, the number of members elected under the majority system has increased from 146 to 148, and those elected under the proportional system increased from 96 to 100. Accordingly, the total number of members of the House of Councillors has increased from 242 to 248.
The new statutory number will be applied in two phases, starting from the next elections due in 2019 in which one half of the 148 seats under the proportional representation system (i.e., 74) and one half of the 100 majority seats (50) will be renewed. The new 124 members will join the remaining 121 members (whose term is not up in 2019), and the House will have a total of 245 members. The House of Councillors will have the full 248 after a half renewal due in 2022. |
