PARIS 鈥 Prime Minister Michel Barnier on Sunday opened the door to raising taxes on France鈥檚 wealthiest individuals and some big corporations to help close a gaping hole in the public finances, but said he would protect the lower and middle classes.

President Emmanuel Macron鈥檚 office this weekend unveiled a right-leaning which he hopes will break the political deadlock that followed a summer snap election. Its most immediate and daunting task will be to put together a budget for 2025 at a time France is struggling to contain a spiraling budget deficit.

鈥淚鈥檓 not going to further increase taxes on all French people, neither on the most modest, nor on people who work, nor on the middle classes. But I cannot exclude the wealthiest from the national effort to rectify the situation,鈥 Mr. Barnier told France 2 television.

France鈥檚 total debt is at 110% of gross domestic product, or close to 3.2 million euros. Weaker-than-expected tax revenues and higher spending by local governments has left its public sector budget deficit spiraling towards 6.2% of economic output next year if nothing is done to rein it in.

It is in breach of European Union (EU) deficit rules and credit rating agencies are scrutinizing French decision-making carefully.

鈥淎 large part of our debt has been placed on international and foreign markets. We have to maintain France鈥檚 credibility,鈥 Mr. Barnier said.

Mr. Barnier, who was the EU鈥檚 lead negotiator during Britain鈥檚 Brexit negotiations, also said he was also open to changes to Mr. Macron鈥檚 pension reform but that any changes should not undermine the pension system鈥檚 precarious finances.

He said by way of example that he wanted to better take into account the hardships faced by working mothers over the course of long careers and that he was open to the input of employers and unions.

Mr. Macron鈥檚 political opponents on the left and far right have already threatened votes of no confidence against Mr. Barnier鈥檚 government. They say the government is not a reflection of how the French voted in the July poll.

鈥淭his is more Macron. It鈥檚 a government that has no future,鈥 Jordan Bardella, chairman of Marine Le Pen鈥檚 National Rally party, earlier said.

Mr. Barnier鈥檚 government lacks a majority and will need to keep the far-right on side and deter it from voting to bring the government down if it is to survive. Perhaps with that in mind, Mr. Barnier said he would get tough on immigration.

鈥淲e need a European response. We need to take action at home too,鈥 Mr. Barnier said. 鈥淲e need to deal with the immigration issue much more rigorously.鈥 鈥 Reuters
