PARIS — Monday could go down as one of the most important days in the history of the French far right.

It’s the moment judges could crush Marine Le Pen’s dream of winning the presidency, one she has never been closer to realizing, according to opinion polls. Le Pen is on trial for having participated in a scheme to embezzle funds from the European Parliament, and if found guilty could be barred from running for any public office for the next five years. The next presidential election is set for 2027.
