I haven't noticed that. Former Perussuomalaiset (Basic Finns)* leader, Jussi Halla-Aho and academic, has been tweeting even before the invasion that Finland should be sending arms and military equipment to the Ukraine.
The Kokomus (Coalition [Conservative]) are all for strong 'sanctions', together with the RKP (ruotsinkielinen Swedish Speakers), but stops short at that so far. It is the SDP (Social Democratic) ruling party (Prime Minister Sanna Marin) who is hesitating about ditching the Fennovoima (joint nuclear energy) project with Russia, instead settling for a 'wait and see' delayed response. It is now suspended for now but not cancelled.
The Left (Vasemmisto - socialist) are a minority although Li Andersson is enormously popular, as Education Minister, and Foreign Office, Pekka Haavisto, Green Party. It used to be in the old days that the Communist Party ran 'friendship' schemes with Russia and exchange trips but they hardly exist at all any more.
It is not my perception that Finland's 'far right' or even 'far left' have much affinity with Russia.
*The PS - perse for short [the Finnish slang for backside) - are not really far Far Right, more just right of Centre, a bit like UKIP, rather than Britain First or whatever.
The Centre (Keskusta) traditionally represents the agricultural sector and although leftish, is anti-Communist in its constitution, as with the Centre Party in other nordic countries.
President Niinisto did already say he wanted to apply to NATO in his new years day message but didn't specify a date.
It is not so that the PS are in favour of Russia at all AFAICS.
