In an unprecedented move for post-war France, Emmanuel Macron has fulfilled his promise of being a reunifying President by naming a right-wing politician outside of his own party as prime minister.
Earlier Monday in Paris, Macron named centre-right lawmaker Edouard Philippe as prime minister in a further effort to splinter the country's traditional parties and redraw the political map.
Philippe and Macron chose experienced politicians from the left, the center and the right for the main positions.
Le Maire, a pro-European German-speaker, came second to ex-President Nicolas Sarkozy in the battle for the leadership of The Republicans (LR) party in 2014, and finished fifth in the party's presidential primaries previous year. Television presenter Nicolas Hulot was recruited to the ecology ministry and Gerald Darmanin, another Republican, was named budget minister.

The announcement of the government was delayed by 24-hours on Tuesday, officially due to the need to carry out more extensive screening of candidates, but which might also have been down to last-minute negotiations.
Meanwhile, criticism from Socialists and conservative Republicans met the nomination of Philippe as prime minister.
"The election of the new French president offers us here the possibility to bring dynamism into the development of Europe", she said, emboldened after her conservatives won a regional vote on Sunday that boosts her chances of re-election in September.
The source added that the new French government's first cabinet meeting would take place on Thursday.
