Voters turned out in low numbers on Sunday in the second round of France's parliamentary election, where President Emmanuel Macron is expected to win a landslide majority that should allow him to embark on far-reaching pro-business reforms.

The vote comes just a month after the 39-year-old former banker became the youngest head of state in modern French history, promising to clean up French politics and revive the euro zone's second-biggest economy.

Macron's neoliberal En Marche party, known by its acronym LREM, is little more than a year old, yet pollsters project it will win as many as 75 to 80 percent of the seats in the 577-seat lower house.

Turnout, though, was on course for a record low, a sign of voter fatigue after seven months of campaigning and voting — and also of disillusionment and anger with politics.

Interior Ministry data showed turnout reached 17.75 percent by 12:00 p.m. local time, its lowest ever at that time of day for a second round of parliamentary elections since at least 1997.

Polls show Macron is on course to win the biggest parliamentary majority since de Charles de Gaulle's conservatives in 1968.
