Paris (France) (AFP) - The French government was on Tuesday set to take the 2027 budget to debate in parliament, with the opposition Socialists and far right staunchly against it, as the government tries to reassure anxious debt markets while containing public anger over spending cuts.

The lower house of parliament, the National Assembly, is due to begin examining the revenue section of the budget on Tuesday evening.

The debate comes against a volatile political backdrop, with weeks of school protests over education conditions and the eurosceptic far-right National Rally (RN) party eyeing power in next spring’s presidential election.

The government wants to reduce the budget deficit in the eurozone’s second-largest economy to five percent of GDP through 43 billion euros ($48 billion) in spending cuts and other measures.

Opposition parties including the Socialists, who helped secure passage of this year’s budget, have slammed the government’s plan for measures that include slashing healthcare spending and capping pensions.

The Socialists plan to table a motion rejecting the budget at the outset of the debate, likely on Tuesday evening.

While the rest of the left plans to back the motion, which concerns the revenue side of the budget, the RN announced Tuesday that it would vote against, effectively dooming its chances of success.

Prime Minister Sebastien Lecornu unsuccessfully urged the Socialists to withdraw the motion.

In a letter to Socialist leaders, he called for compromise and argued that refusing to engage in budget discussions would be “the worst signal the National Assembly could send”.

The Socialists rejected the offer, with lawmaker Melanie Thomin accusing Lecornu of keeping “the door firmly shut to any measure of tax fairness in the name of sacrosanct stability.”

- ‘Confrontation’ -

The far right said it would not back the motion.

“We want a debate, and we will not give the Macron government the gift of avoiding a confrontation in the chamber,” said Jean-Philippe Tanguy, a senior National Rally lawmaker.

Public Accounts Minister David Amiel called the planned move “a boycott motion”.

“Interest rates are soaring today. Parliament cannot simply look the other way,” he told broadcaster France 2. “We need a debate in the National Assembly.”

French government bonds have become the bane of investors amid fears that officials are unwilling or unable to rein in spending that far outstrips revenue.

Mounting concerns over France’s finances have fund managers demanding higher returns for lending to France, resulting in a surge in borrowing costs that could spiral into a full-blown debt crisis.

“Financial markets need to feel that, whatever happens, we’ll ultimately end up at five percent,” a government source said, referring to the deficit-to-GDP level.

Whether debate drags on for weeks or is cut short, the government has little prospect of securing passage of the budget through parliament under normal parliamentary procedures.

- ‘More market pressure’ -

The government wants to almost halve its social security deficit next year, bringing it down to 12 billion to 13 billion euros.

Among other measures, it is proposing that annual revaluations of pensions above 1,260 euros a month no longer be fully indexed to inflation.

The plan has drawn criticism from across the political spectrum, spanning the hard left, the far right and the conservative Republicans.

Lacking a parliamentary majority, the government could once again use a constitutional power to ram the legislation through parliament without a vote, as it did last year.

Bruegel, a Brussels-based think tank, said the bond market exposed a French economic problem that has been building for years.

“France may need to experience more market pressure before its political system is willing to accept reforms it has postponed for years,” its analysts said. “Much greater stress may be what ultimately makes a broader governing agreement feasible.”
