PARIS (AP) – France’s new President Emmanuel Macron is formally taking power Sunday during a ceremony at the Elysee presidential palace in Paris.

His predecessor, Francois Hollande, is to welcome him in the courtyard in front of hundreds of journalists. The two were meeting in the president’s office before Hollande’s departure, taking a last few minutes to discuss the most sensitive issues facing France, including the country’s nuclear codes.

Macron takes charge of a nation that, when Britain leaves the European Union in 2019, will become the EU’s only member with nuclear weapons and a permanent seat on the U.N. Security Council.

Macron will then make a speech in the Elysee reception hall in front of about 300 guests, officials and family members, including his wife Brigitte Macron. She will be wearing a lavender blue dress by French designer Nicolas Ghesquiere for Louis Vuitton.

Macron will be wearing a dark suit from French brand Jonas and Cie, a tailor based in Paris, that cost 450 euros ($491), his team said.

Following the ceremony and military honors at the Elysee palace, Macron will go the Tomb of the Unknown soldier, at the Arc de Triomphe at the top of the Champs-Elysees Avenue, a tradition followed by all heads of states in France’s modern history.

Macron will also meet with Paris Mayor Anne Hidalgo later Sunday.

His first visit abroad will be to Germany on Monday, to visit with German Chancellor Angela Merkel in Berlin.

He will have to name his prime minister and form a government in the following days.

A former economy minister, Macron quit Hollande’s Socialist government last year to launch his independent bid. He is the first French president who doesn’t originate from one of the country’s mainstream parties.

He has promised to reinvigorate French politics by bringing in new faces. His Republic on the Move movement has announced an initial list of 428 candidates for the 577 seats up for grabs in France’s lower house of parliament in June. Macron is seeking a majority of lawmakers so he can pass his programs.

Many of the Republic on the Move candidates are newcomers in politics. Their average age is 46, compared to 60 for the outgoing assembly. Half of them are women. Only 24 are lawmakers running for re-election, all Socialists.
