PARIS—Anti-immigrant leader Marine Le Pen is engaged in a high-stakes game of chicken with the French government and a multitude of global investors who finance the country’s sizable debt load.For weeks,

France’s government offered a final-hour concession to Marine Le Pen on the 2025 budget, seeking to avoid being ousted from power in a no-confidence vote that would plunge the country into financial and political uncertainty.

Marine Le Pen, National Rally (RN) leader, has threatened to bring down the French government on Monday if Michel Barnier, France’s prime minister, does not drop effective cuts to pensions.

French Prime Minister Michel Barnier is bracing for a no-confidence vote this week, a political reckoning poised to topple his fragile government and send shockwaves across the eurozone.

France's Michel Barnier faced an abrupt end to his premiership Monday after key opposition parties said they would back a no-confidence motion against his government after only three months

Opposition to Barnier has intensified in recent weeks, culminating in a Monday move by the prime minister to try and “ ram ” a social security bill through parliament without a vote having failed to get the support of Marine Le Pen’s National Rally for the bill.
