Rosen Zhelyazkov's Bulgarian coalition government resigned following widespread anti-corruption and anti-tax-rise protests across the nation, marking a significant episode of political instability.The protests, drawing tens of thousands of young Bulgarians, were directly triggered by a proposed budget that would have increased taxes and social security contributions to fund greater state spending.This resignation, approved by the Bulgarian Parliament, occurred weeks before the country's scheduled euro zone entry and highlights persistent deep divisions, making an eighth election since 2021 likely.
