Graphical summary
Poll results
Poll results are listed in the table below in reverse chronological order, showing the most recent first. The highest percentage figure in each poll 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 table uses the date the survey's fieldwork was done, as opposed to the date of publication. However, if that date is unknown, the date of publication will be given instead.
