The party's ideological character is contested by political scientists, though it is widely considered to be populist in nature. After being formed predominantly as an anti-corruption vehicle, the party has at different times been considered centrist, liberal, conservative, right-wing, social democratic[17] or centre-left[18] by different commentators, leading to a further characterisation as a syncretic or catch-all party. Since the 2024 European Parliament election, the party has positioned itself to the right, co-founding Patriots for Europe, a group in the European Parliament that is made up of Eurosceptic parties that primarily adhere to national conservatism and right-wing populism.

It’s only populist party.

If it is "only a populist party" (there is no such thing, since populism is a political strategy, not an ideology), why did you start out by claiming it was a leftist populist party?
