French President Emmanuel Macron's year-old party Republique en Marche (Republic on the Move, LREM) has secured a huge majority on 18 June in legislative polls.
Macron who became France's youngest-ever president just over a month ago led his party to victory, crushing the old parties that have dominated French politics for decade.
The party and a smaller ally will control some 360 seats in the 577-seat National Assembly, according to France 24.
However, Macron's success was marked by record low turnout of just under 44 percent.
For the first time in history, turnout in a legislative election has slumped to below 50 percent, in both rounds. On Sunday, a mere 43 percent of voters casted their ballots.
The measly turnout reflected voters' widespread disgust with the mainstream parties of right and left that have dominated French politics for decades, according to the report.
Meanwhile, Far-right leader Marine Le Pen, runner up in the presidential election, won a seat in parliament for the first time.
She won her northern constituency of Henin-Beaumont with a large majority and said would "fight with all necessary means the harmful projects of the government."
