France's government looks on the brink of collapse. What's next?

PARIS — France's minority government appeared to be in its final hours Tuesday as opposition lawmakers from the left and the far right vowed to topple Prime Minister Michel Barnier's Cabinet.

A no-confidence vote is scheduled Wednesday in parliament in the wake of a divisive budget debate, with a strong chance of being successful.

If the motion passes, Barnier's Cabinet would be the shortest-lived government in France's modern history, marking an unprecedented period of political instability.

President Emmanuel Macron would be in charge of appointing a new prime minister.

Why is the situation so volatile?

Following the June-July parliamentary elections, the National Assembly, France's powerful lower house of parliament, is divided into three major blocs: a left-wing coalition known as the New Popular Front, Macron's centrist allies and the far-right National Rally party. None won an outright majority.

In September, Macron asked Barnier, a conservative, to form a government dominated by Republicans and centrists — implicitly relying on the far right's goodwill to be able to stay in power.

Meanwhile, the left-wing coalition denounces an ''austerity budget'' and criticizes ''the absence of dialogue and disregard for parliamentary work."

The National Assembly said the no-confidence motion requires a majority of the votes to pass — or at least 288 of 574 lawmakers currently in office.

Altogether, the left and the far right count over 330 lawmakers — yet some may abstain from voting.

What if the government falls?

Wednesday could see the first no-confidence motion succeed in over six decades.

The parliament's fractured composition would remain the same. No new legislative elections can be held before July, because under the French Constitution, the National Assembly must remain in place for a minimum of one year.

No favorite figure to replace Barnier has emerged yet. Macron could pick a politician from his centrist alliance, French media report.

The New Popular Front asks for a left-wing Cabinet to be appointed instead.

Some opposition lawmakers are calling for Macron to resign, but the French president has previously ruled out that option.

How about the budget?

An outgoing government could present a special law to levy taxes from Jan. 1, based on this year's rules. It would also be able to decide on renewing spending by decree in order to pay civil servants, pensions and other key government expenses.

However, this would suspend any potential tax hike — like one initially expected on big companies — and freeze any new spending.

In particular, an additional 3.3 billion euro ($3.5 billion) package for the French military was planned as the country supports Ukraine in its war against Russia.

Later, a new government could present its own budget proposals at parliament.

Why are markets spooked?

France is under pressure from the European Union's executive body to reduce its colossal debt. The country's deficit is estimated to reach 6% of gross domestic product this year and analysts say it could rise to 7% next year without drastic adjustments.

The political instability could push up French interest rates, digging the debt even further.

In addition, without a clear parliamentary majority, no major reform appears within the reach of a new government.
