bi cameral parliament. a political party needs 5% of the vote to get in. an independent needs like 100k iirc. there is no regional designation. parties make a list for all possible seats and order them. they get as many seats as percentage of the vote after the people who don't make 5% get removed. minorities get a set of guaranteed seats. if a seat holder gets impeached or works somewhere else the next on the list takes his place.
