Difficult to find an all encompassing bag in which to put all of these `gentlemen . (the Danish equivalent is however a woman, Pia something, forgot her name,she took over after the less than savory Glistrup.) We have so far been spared them up here-we had the buffoons of New Democracy a few years back, led by a well know light entertainment promoter, Bert Karlsson and Ian Wachtmeister but they soon imploded.Norway has them too,where they are led by Hagen. I think they are the second biggest party there but I could be wrong about that.
I would suggest Poujardist? Though in reality they represent a paradigm shift on the right and they seem to represent about 15% of the population generally on avarage in western Europe. In the good old days you could tell these people by the colour of their shirts!
However I hope not to upset you too much when I suggest that sometimes they are Ùbuesque! B) Glistrupp was anyway...
Actually I am not sure I would include Berlusconi on this list, though I would include his ally Bossi of the Northern League and perhaps Fini or whoever now leads the old MSI,though they ,having changed their name are trying to reinvent themselves as a respectable coservative party, much like the old Stalinist left didwhen they became good social democrats
