Nationwide polling

Polling

Poll results are listed in the table below in reverse chronological order, showing the most recent first. 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, parties are shaded with their colour. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. Poll results use the date the survey's fieldwork was done, as opposed to the date of publication.

Polls that show their results without distributing those respondents who are undecided or said they would abstain from voting, are re-calculated by removing these numbers from the totals through a simple rule of three, in order to obtain results comparable to other polls and the official election results.
