The 81 members of Parliament were elected by proportional representation from a single nationwide constituency with an electoral threshold of 3%, although the threshold was reduced to 0.7% for ethnic minority parties in districts where ethnic minorities accounted for at least 15% of the population.

Poll results are listed in the table below in reverse chronological order, showing the most recent first, and using the date the survey's fieldwork was done, as opposed to the date of publication. If such date is unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. When a specific poll does not show a data figure for a party, the party's cell corresponding to that poll is shown empty. The threshold for a party to elect members is 3%.
