After several years under the shackles of a mostly FPTP electoral system, there is now hope that South Korea could inch towards a more democratic system as the ruling Democratic Party and three minor opposition parties agreed on a draft to introduce a revised mixed-member proportional representation system. Currently 253 seats are distributed with the autocratic FPTP-system, and 47 seats are distributed proportionally (not as top-up seats). With the new system, 225 will remain as FPTP-seats while 75 seats will be divided proportionally. However, if these are, as rumoured, compensatory seats, then the final result will be closer to the proportionality one must expect of a modern, democratic electoral system.
