New German Chancellor Friedrich Merz announced a reset in French-German relations to help Europe overcome the "enormous" security and economic challenges it faced during his first trip abroad since taking office to top ally France on Wednesday.

Germany’s Friedrich Merz has formally become chancellor at the second attempt, hours after an unprecedented defeat signaled deep discontent within his coalition.

Supporters of Mr. Merz, a former corporate lawyer, say he is well-prepared and thoughtful, but critics accuse him of failing to think more than one step ahead and breaking promises.
