Germany's centre-right CDU/CSU bloc has won national elections by a large margin, with all constituencies counted, paving the way for leader Friedrich Merz to be the next chancellor, as could be seen on the website of the federal returning officer.

Christian Democratic Union (CDU) leader Friedrich Merz is poised to become Germany’s next chancellor based on preliminary election results, but he remained cautious about the prospect as his party celebrated its victory on Sunday.

Trump's statements on Ukraine last week make it "clear" Americans are "largely indifferent to the fate of Europe," Merz said.
