Marine Le Pen’s ultimatum to French Prime Minister Michel Barnier, even after he caved on a key demand from her party, lays bare the unprecedented clout the far-right leader now wields in Paris’ halls of power.

It wasn’t long before the longtime face of the French far right flexed her muscle again with yet another threat over her demands that Barnier adjust the budget: "Today is Thursday. He has until Monday,” Le Pen told Le Monde.
