Farmers in Poland will use their vote in the Sunday, May 18th presidential elections to vent their anger at the European Union, which has let them down with its debilitating green regulations and by allowing the import of cheap Ukrainian agricultural products.

At last year’s European elections, Polish farmers voted overwhelmingly for right-leaning parties that pledged to protect them: 61.9% of them for the opposition conservative Law and Justice (PiS) and 15.5% for the right-wing Konfederacja.

In the first round of Sunday’s presidential election, independent conservative candidate Karol Nawrocki—supported by PiS—can also count on the support of the farmers.

He has called EU climate policies an “existential and fundamental” threat to Poland’s economy and sovereignty, and has vowed to hold a national referendum on the European Green Deal,which he says jeopardises the livelihood of Polish farmers and urban residents alike.
