May I suggest the Swedish Peoples Party in Finland. They are a Liberal Party, more than Centre and are unequivocally pro European. They're not separatist either (which is clearly an issue for you). They're who I'd vote for over there.
Yeah, separatism and nationalism in general are an issue for me, probably because I'm Spanish. Yeah, they seem a nice fit, will change that. Thanks!
Also, wow, I didn't think I'd be so transparent
The Australian Democrats are largely non-existent these days, I can see you being a small l-liberal voter in Australia, voting for the likes of Malcolm Turnbull, although I can see you voting for Labor against the likes of Tony Abbott.
Well, I was searching for a centrist party in Australia. So I'd be more of a swing voter between Labour's right and Liberal's wets? Thanks for the info.
