Political leaders across Europe congratulated conservative leader Friedrich Merz after Germany's parliament elected him Tuesday as chancellor in a second round of voting.

European Council President Antonio Costa extended "warm congratulations" to Merz, saying he is looking forward to their work together on an ambitious common European agenda.

Congratulating Merz, French President Emmanuel Macron said “it is up to us to make the Franco-German engine and reflex stronger than ever."

“It is up to us to accelerate our European agenda of sovereignty, security and competitiveness. For the French, for the Germans, and for all Europeans," he wrote on X.

British Prime Minister Keir Starmer also congratulated Merz.

"I look forward to working together to deliver national and economic security for people in both our countries," he wrote on X.

Italian Prime Minister Giorgia Meloni also congratulated Merz, saying cooperation between their countries is crucial for addressing global challenges.

“Our two Nations, Europe’s leading manufacturing economies, can make a decisive contribution to reviving competitiveness – starting with the automotive sector – and to building fair partnerships with Africa, as well as combating irregular immigration,” she said on X.

Micheal Martin, the Irish taoiseach (prime minister), said Germany is a valued friend and partner of Ireland, noting that he is looking forward to working with the new chancellor to deepen ties between Berlin and Dublin and "to make Europe stronger, safer and more prosperous."

Belgian Prime Minister Bart De Wever expressed his "heartfelt congratulations" to Merz and said he looks forward to close cooperation with the new German government, as neighbors and in Europe.

"A shared border also means shared responsibility," said Austrian Chancellor Christian Stocker in his congratulatory message, adding he looks forward to friendly cooperation between the two governments.

Danish Prime Minister Mette Frederiksen said on X that she looks forward to strengthening the close ties between Germany and Denmark and to cooperate on ensuring a stronger and more resolute Europe.

Spanish Prime Minister Pedro Sanchez said Germany and Spain have always shown their commitment to the European project with shared interests and goals.

“Let us continue working for a united and strong Europe," he said on X.

Polish Prime Minister Donald Tusk was also among the European leaders to congratulate the new German chancellor.

Dutch Prime Minister Dick Schoof said he "warmly congratulates" Merz, adding for the Netherlands, close ties with their neighbors are of great importance.

"I look forward to continuing the close cooperation with Germany under Chancellor Merz, including within the EU and NATO," he wrote on X.

Vjosa Osmani, the president of Kosovo, said that at a defining moment for Europe’s unity and security, Germany’s "continued leadership is more vital than ever."

"As one of Kosovo’s most important allies, we look forward to strengthening our partnership and working together to advance Kosovo’s rightful path toward EU and NATO membership," she said on X.

NATO Secretary-General Mark Rutte also congratulated Merz, saying his leadership will be "crucial" as they work to ensure that allies are ready and able to deter and defend to keep their people safe.

Merz, after getting parliamentary approval on Tuesday, became Germany's 10th chancellor since World War II. He secured this position after his Christian Democrats clinched a coalition deal with the Social Democrats following Feb. 23 snap elections.

In the new coalition government, the conservative CDU/CSU alliance will oversee crucial portfolios, including the foreign, interior and economy ministries. The Social Democrats will head seven ministries, including finance, defense and labor, according to the agreement.
