Thousands of Polish farmers protested outside the prime minister’s office in Warsaw on March 6, burning tyres and throwing firecrackers as they demanded a halt to cheap imports and environmental regulations they say harm their livelihoods.Protesters burned tyres and ignited flares in front of Donald Tusk’s office, while elsewhere in the country they blocked roads and stopped traffic on the outskirts of the capital.Farmers across the European Union have been calling for changes to restrictions placed on them by the bloc’s Green Deal plan to tackle climate change and for customs duties on imports of agricultural products from Ukraine that were waived after Russia’s invasion to be reimposed.In Poland, this has created a delicate balancing act for Donald Tusk’s government in a year where it faces both local and European elections, as it seeks to address farmers’ concerns while also maintaining its staunch support for Kyiv.The farmers are now backed by Poland’s biggest labor union NSZZ Solidarnosc, as well as hunters and forestry workers.
