Mateusz Morawiecki served as prime minister of Poland from 2017 to 2023 as a leading figure in the Law and Justice party. Opponents frequently accused him of dishonesty during debates over the economy, courts and European Union relations. The phrase judasz, kłamca, Polish for Judas, liar, became a shorthand insult in opposition posts, comment sections and edited clips shared on social media. Short political phrases like this spread because they summarise distrust in a few seconds and can be reused whenever his speeches or interviews are quoted online today.
