PARIS — Emmanuel Macron and Marine Le Pen represent sharply contrasting visions for the future of France — and of Europe — showcased in a bruising debate on Wednesday ahead of the final round of the country’s presidential election on Sunday.

Ms. Le Pen, the far-right candidate of the National Front, is campaigning on a bellicose security platform, emphasizing her anti-immigration, anti-European Union, anti-globalization bona fides. Mr. Macron, a former economy minister and investment banker, is pro-business, in favor of free trade and open to reinforcing economic and security ties with Europe.

Here is a breakdown of the candidates’ divergent views on major issues.

The State of Europe

“The European Union is going to die, because the people don’t want it anymore.” — Ms. Le Pen

Ms. Le Pen has pledged to hold a national referendum on taking France out of the bloc — a so-called Frexit, which is widely seen as a trigger to the breakup of the European Union. She also wants France to abandon the euro, which she called “the currency of bankers,” and bring back a national currency — an idea that has rattled business leaders and financial markets. She has declared her intention to begin negotiations with Brussels to overhaul European institutions as soon as she is elected, and said she would pull France out of European trade agreements that, in her view, harm its interests.
