Greece did something similar a few years ago.
The Golden Dawn far right wing party was declared a criminal organization (after some violence that lead to a few stabbings and at least one death) and their leaders were thrown in jail.
From the ashes of Golden Dawn and a few other populist/Christian conservative/nationalist parties rose a few new ones, with more careful rhetoric and open support from the now jailed golden dawn leaders and high ranking church ministers.
They are collectively holding 26 of the 300 seats in the parliament and are expected to get better results on the next election cycle.
You can ban them all you want, they can still reform into a “we are not far right, wink wink” party after the ban itself verifies their far right status and rise to power all the same.
I’m sure they all “volunteered”
