PARIS — The Paris prosecutors’ office opened an investigation into the campaign financing of far-right leader Marine Le Pen’s presidential bid in 2022.

Marine Le Pen's far-right National Rally (RN) party scored historic gains to win the first round of France's parliamentary election on Sunday, exit polls showed, but the final result will depend on days of horsetrading before next week's run-off.

Emmanuel Macron was elected to a second term as French president on Sunday evening with 58.8% of the vote, according to an estimate from the Ipsos polling institute. His far-right challenger Marine Le Pen won 41.2% of the vote in an election that saw the country’s highest abstention rate in 50 years. Read our live blog to see how all the day's events unfolded.

“I want France to leave NATO’s unified military command. I will never agree that our troops are subordinate to the NATO command or the European command. France should return to the status in the alliance that it had from 1966 to 2009,” the French presidential candidate said.

French President Emmanuel Macron will face Marine Le Pen in the second round of the country's presidential election, setting up a rematch of their runoff contest in 2017.
