FKP) or New Communist Party of Finland (Finnish: Uusi Suomen Kommunistinen Puolue, abbr.

It was founded in the mid-1980s as Communist Party of Finland (Unity) (Finnish: Suomen Kommunistinen Puolue (yhtenäisyys), abbr.

After the 20th party congress in 1984 things, however, changed as Arvo Aalto was elected chairperson, after which the opposition did not participate in (or was left out of) the SKP central committee.

The ambiguities in the expelling process and the opposition's firm belief in its own cause gave it the justification it needed and they considered SKPy to be the real SKP.

On 26 April 1986, a meeting of "the representatives of SKP organizations" was held in Tampere and those present elected a new central committee.

Yrjö Hakanen and Marja-Liisa Löyttyjärvi became the vice chairmen while the former SKP chairman Jouko Kajanoja was elected party secretary.

In his congress speech, Sinisalo told that the suffix "unity" meant "strong intention to gather all the forces of the SKP".

SKPy was very committed to the Soviet Union and the political line of its Communist Party (CPSU), which was going through great changes during Gorbachev's time.

Communist Workers' Party – For Peace and Socialism (Kommunistinen Työväenpuolue – Rauhan ja Sosialismin puolesta, KTP) was founded early in the year 1988.

Founders of KTP felt to be securing the existence of a Marxist-Leninist party in Finland while criticizing SKPy for being revisionist and supporting Mikhail Gorbachev.

The most famous figure in the new party was probably Markus Kainulainen, a longtime SKP district secretary of Uusimaa and a former MP.

Esko-Juhani Tennilä, a member of the Parliament of Finland, was elected new chairman of SKPy 22 October 1989 when Kajanoja decided to resign while strongly criticizing his comrades.

The Left Alliance (Vasemmistoliitto) was founded in spring 1990 and members of SKPy and its electoral front Deva also joined even though prejudices were very high on both sides at this point.

The dispute over double membership, as it was called, led to many SKPy members leaving LA and relations between the two parties got even colder.

In the congress, the suffix "unity" was dropped from the name as SKPy now considered to consist of all those comrades who wanted to have an independent communist party.

The decision split the party as some supporters would have preferred SKP to have a lesser role as "Marxist forum" of some kind.

While SKPy was never officially registered, its supporters founded an electoral front Democratic Alternative (Demokraattinen vaihtoehto, syllabic abbreviation: Deva).

Those MPs of Finnish People's Democratic League (Suomen kansan demokraattinen liitto, abbr.

It was the first time the Finnish electorate had an opportunity to vote for a list named Communist Party of Finland.

In 2003, the vote-puller for the party was rock musician Kari Peitsamo (1,803 votes) and in 2007 rap artist Seppo "Steen1" Lampela (1,842).
