The centrist party of French President Emmanuel Macron looks set to win a landslide victory in the second round of parliamentary elections on Sunday.
Projections show La République en Marche (Republic on the Move or LREM) and its MoDem allies are set to win 75-80% of seats.
The run-off features the top candidates from last week's first round.
Traditional parties are urging voters to back Macron's rivals to stop a monopolisation of power.
A party needs 289 seats to control the 577-seat National Assembly. LREM is predicted to win more than 400.
Macron won the presidential election last month and he is now hoping to secure a solid majority to help push through his planned reforms for the country.
He formed his party just over a year ago, and half of its candidates have little or no political experience.
They include a retired bullfighter, a Rwandan refugee and a mathematician.
