Electoral system for national legislature

OSCE, Greece Parliamentary Elections October 2019, ODIHR Needs Assessment Mission Report, 10-12 April 2019, accessed 10 July 2019

“For these elections, members of parliament will be elected for four-year terms through a proportional system with compensatory seats. Seat allocation is calculated at both the national and constituency levels: 238 deputies are elected through an open list with preferential voting across 59 multi-member constituencies, while 12 deputies are elected on closed party lists based on the nationwide proportion of votes. The 50 remaining “bonus” seats are allocated to the party with the most votes. To be eligible for seat allocation, a party or independent candidate must obtain at least three per cent of valid votes nationwide.”
