Marine Le Pen banned from running for French presidency in 2027 and given four-year sentence in embezzlement trial – live

If by recent years, you mean the last 20+ years, sure.

I'm not sure it truly hurts the Front National chances in 2027, however, the expected heir, Jordan Bardella, is not nearly as smart as MLP, so maybe it will make enough of a difference if it ends up a close thing. I would say the political situation in France is pretty volatile, hard to say what it will look like in 2 years.

There is also the possibility (slim, imho, but still real) of MLP either winning her appeal (which should take place sometime in 2026), or at least having the ineligibility sanction removed, which I think would give her a huge boost.

Financing parties is complicated by design as the French system tries to avoid interference from companies or wealthy individuals. RN was struggling because they are greedy incompetent pigs. So they decided collectively to use the money dedicated by the European parliament to recruit parliamentary assistants to finance the party's activities. And they got caught.

This won't affect their chances as racist voters will still vote for racist candidates, whatever the candidate. We will just have a new racist guy (Jordan Bardella) instead of Le Pen.

It's not so recent. Her father was in the second turn of the presidential election in 2002. Still the RN (rassemblement National) far right party is bigger than ever with 123 elected member in the National assembly (out of 575). They don't really have a back up. She took the reigns from her father, she is the name of the party. The second (Bardella) is young and inapt, and he also has some problem with the law (fake work)
