We had a similar party here in Denmark, that became second largest party of the country with 21% in 2015, When the government introduced tough restrictions on immigration, they almost vanished a few years later, only very narrowly managing the 2% minimum requirement to have seats in parlament.
The popularity of the party was highly based on limiting immigration, much like Brexit, Trump, AfD and AFAIK also RN of France.
That’s what it looks like to me. Italy too AFAIK.
