French President Emmanuel Macron is due to announce the first measures he plans to take following the national consultation process launched in response to the Yellow Vests protest movement.
Macron's office says he will make a speech to the nation at 8:00 pm local time (0400 AEST Tuesday).
The centrist president, who tends to keep the media at arm's length, will also hold a rare domestic press conference on Wednesday.
The "great national debate," which ran from January to March, involved more than 10,000 local meetings as well as 16,337 "books of grievances" in town halls around the country.
More than 500,000 people made policy suggestions online on a dedicated website.
Prime Minister Edouard Philippe has promised tax and public spending cuts in response to the debate, but the left-wing opposition accuses him of a partisan interpretation of the results.
The Yellow Vests movement initially opposed planned fuel tax rises, but has raised broader demands for lower taxes, higher pay and more direct democracy since those tax hikes were cancelled.
Protests every Saturday have seen repeated clashes with police in Paris and other cities, though the numbers protesting - according to government estimates - have dropped gradually from 280,000 in November's first protests to 31,000 last weekend.
