In the beginning of 2019, we provided a highly informative trend analysis for the EP election in the Czech Republic. The same approach was successfully implemented in 2020 to analyze trends defining the regional election. Our aim was to publish a trend analysis also for the 2021 parliamentary election but unfortunately, we are not able to do so. The coalitions formed for this election are so different from those standing in the previous cases that the historic time series cannot be used properly and correctly. We regret to inform, that we cannot do more than continue the comparative analysis of election models as published by Czech pollsters.
