Friedrich Merz, the leading candidate for the chancellery in Germany's upcoming election, said a leaked briefing by Germany's ambassador to the United States heavily criticising Donald Trump was damaging to the German government's reputation.

BERLIN (Reuters) - German opposition leader Friedrich Merz, tipped to become chancellor in next month's election, said on Tuesday U.S. President Donald Trump could prove an interesting partner for Europe provided the region had a strong common negotiating position.

Friedrich Merz, front-runner to become Germany’s next chancellor, called incoming US President Donald Trump a “very predictable leader” with a clear agenda who’ll force Europe to carry out necessary reforms more quickly.

Outgoing Vice Chancellor Robert Habeck says the EU and Germany must show unity in the face of potential US tariffs under Donald Trump. He told DW that trade conflicts with the US would be to the detriment of both sides.
