Alternative for Germany (AfD) has achieved its best-ever election result in Saxony-Anhalt, prompting celebration from Europe's populist right and sharp criticism from Poland's prime minister. The far-right party's regional success has raised alarms across the EU, with analysts warning of growing political shifts. The BBC's Europe editor Katya Adler highlights the significance of the result, suggesting it could signal broader challenges for traditional political forces. The Economist notes the AfD's improved performance, indicating a potential shift in Germany's political landscape. This development has sparked discussions about the implications for European unity and democratic stability.
