French Prime Minister Michel Barnier's government could collapse after three months in power due to a coalition of right- and left-leaning political parties opposing a recent budget move.

The fall of France's government on Wednesday and the failure to pass a budget could make it difficult for Paris to ramp up its support for Ukraine despite President Emmanuel Macron's repeated promises to help Kyiv for as long as necessary.

Already struggling with flat growth and a large debt and deficit, the country faces a new period of instability without a functioning government or a budget.
