French voters cast ballots with few signs of enthusiasm overnight in the final round of a parliamentary election that could clinch President Emmanuel Macron's hold on power - his fledgling party is hoping to rout mainstream rivals and upend politics as usual in France.
Pollsters say after its dominant performance in last week's first-round vote, Macron's Republic on the Move! party could win up to 450 seats Sunday in the 577-seat National Assembly, the powerful lower chamber. The low turnout rate trending Sunday could help do the job.
If the steamroller effect continues for Macron's party, half of whose candidates are women and half new to politics, France will have a chamber of representatives like few others, fulfilling the president's wish to renew a political class that for years has been dominated by career politicians and peppered with corruption.
The strong mandate would also give the 39-year-old president, elected in May, a free hand to move fast with promised legislation, notably on changing labor laws to make hiring and firing easier.
Pollsters' predictions far surpass his need for an absolute majority - 289 seats - a prospect that worries both rivals and some voters.
Macron's party has 513 candidates vying for 573 seats. Four seats were won outright in last Sunday's first round.
While French voters have handed presidents large majorities in parliament in the past, this time Macron's party is splitting - and therefore weakening - the opposition.
Voter turnout was trending low by late afternoon. The Interior Ministry said just over 35 per cent of voters had cast ballots. That was down from 41 per cent at the same time in the first round and down from nearly 46.5 per cent in the last parliamentary elections in 2012.
In the first round of the two-part vote, less than half of France's 47.5 million-strong electorate voted last Sunday, hurting the once-feared far-right National Front party of Marine Le Pen, runner-up to Macron for the presidency.
Six ministers in Macron's government are seeking parliamentary seats, a common practice in France, and risk their government jobs if they lose.
Candidates from the conservative party, The Republicans, are expected to form the largest opposition group, with 70-110 seats, according to pollsters, with other parties sharing the rest.
The Socialists, who dominated the outgoing Assembly with 314 seats, have been annihilated by the unpopularity of former President Francois Hollande and could win as few as 20 seats.
The National Front is expected to win only a handful of seats despite its third-place showing in the first round. The populist Le Pen appears likely to win in her northern bastion.
The National Front had two seats in the outgoing parliament and the only lawmaker seeking to renew his mandate, Gilbert Collard running in the southern Gard region, could lose.
His opponent, a former bullfighter representing Macron's party, got a public boost this week from visiting Prime Minister Edouard Philippe.
