The National Assembly passed a new reform bill on 27 December 2020 designed to adopt a new proportional representation system. Under the new bill, the number of directly elected seats and PR slots are kept at 253 and 47, respectively, in the 300-member National Assembly. However, the new bill partly eliminates the Parallel system and introduces MMP system instead. The number of PR posts to be allocated under the MMP representation scheme will be capped at 30.
