With the upcoming date of the referendum on the entry of the CZ to the EU, we have been monitoring flows between the group of those that claim they will "definitely" participate and those that are not completely certain about their participation and chose the answer option "will more likely participate in the referendum on the entry of the CZ to the EU”. However, the number of those that say they will participate in the referendum has not changed much since the end of last year and in April 78 % of respondents declared their participation.
