The fall of the French government and failure to pass the budget could make it difficult for Paris to increase its support for Ukraine despite the president's repeated promises Emmanuel Macron to help Kiev as long as necessary.
In November, France completed training about 2,000 Ukrainians, including providing armored troop movement and reconnaissance vehicles, Caesar howitzers, anti-tank missile launchers, surface-to-air missiles and battlefield radars.
It has also shipped new missiles in recent weeks, using funds from frozen Russian assets, and plans to deliver Mirage fighter jets in the first quarter of 2025.
However, Defense Minister Sébastien Lecorneau, a potential future prime minister, said as early as October that France would not fulfill the promise of 3 billion. euro ($3.16 billion) for 2024, and the amount will be over 2 billion. euro.
Speaking ahead of Wednesday's no-confidence vote, which saw Michel Barnier's government collapse, Lecorneux said it would affect France's support for Ukraine.
"A large part of the support for Ukraine is the transfer of old equipment from the French army, which is then replaced with new ones," Lecorneau told the newspaper "Parisien".
"If we delay the order of new equipment, then we will have a delay in supplies to Ukraine,", the defense minister summed up.
If the 2025 budget not be adopted, which essentially means that the 2024 budget will take effect next year, the defense budget will fall short of its $50 billion target. euro and will mean a loss for the army of 3.3 billion. euro, Lecorneau said.
