In a stormy session of the Bundestag, Merz called the AfD a 'destructive force' and directly challenged Weidel, whose party won almost 44% of the vote in Sunday's state election. The chancellor's conservative bloc saw its vote share halved in Saxony-Anhalt, a result Merz described as 'seismic' and one that has changed Germany.
Weidel told MPs that voters had shown Merz's coalition with the centre-left was a total failure and that his time was up. The AfD leader was repeatedly heckled by her own party's MPs as Merz responded.
Merz argued that one in six skilled workers has a migration background, and that the AfD's 'remigration' policy—a term the party uses to describe the deportation of irregular migrants—would affect millions. 'If her party had its way, its policy would amount to nothing other than an ethnic cleansing in the skilled trades based on skin colour and origin,' Merz said.
While the government acknowledges some deportations are needed, Merz said it makes a careful distinction between those who contribute to German prosperity and those without permanent residency. The AfD in Saxony-Anhalt has been labelled 'right-wing extremist' by German domestic intelligence and has promised a 'deportation and remigration' offensive.
It remains unclear whether the AfD will be able to form a government in Saxony-Anhalt, having fallen three seats short of an outright majority. No far-right party has held power in any of Germany's 16 states since World War Two.
The AfD's success drew praise from US President Donald Trump, who said 'the Populist Party in Germany just had a really big night,' linking the victory to 'absolutely horrible immigration rules and regulations.'
Disruption by AfD MPs became so loud during the debate that Bundestag President Julia Klöckner threatened to start expelling people from the chamber.
