There were definitely parties in the Netherlands and France that made leaving the EU their major plank. When Brexit turned out to be rather more difficult than its adherents imagined, support for "Frexit" and "Nexit" plummeted like a rock, and hasn't recovered.

Greece is slightly more plausible, but less because Greece wants to leave and more because the rest of the EU decides to kick them out. It's doubtful they'd kick them out of anything more than the Eurozone, though.
