Greek supermarket chains have imposed limits on the purchase of flour and sunflower oil due to increased demand and concerns over potential supply issues caused by the war in Ukraine. The restrictions are part of wider concerns about product shortages across the European Union, with Russia and Ukraine being key suppliers of these commodities. The Greek government has asked suppliers to declare stockpiles of various products and is planning to discuss potential shortages further with Prime Minister Mitsotakis. Similar restrictions have also been implemented in Spain and Italy.
