The political group chaired by businessman and MP Harry Harkimo, Movement Now (Liike Nyt), announced on Monday that it had collected the necessary 5,000 signatures needed to officially register as a political party.
The group said it plans to hand over the supporters' cards to the justice ministry on Friday. Movement Now began collecting signatures from supporters last month.
At the time, Harkimo - who first started the group soon after his 2018 departure from the National Coalition Party with six other non-career MPs - said the movement claimed no direct political role models, and distanced it from party politics.
However, last April, Harkimo ran and won a seat in parliament as a candidate nominated by a Movment Now electors' association.
Influence cited as motivation
The group has said their motivation for becoming an official party was in order to have more influence. Due to its lack of official party status, Movement Now candidates - as well as other non-sanctioned groups - were not included in parliamentary debates or voter support polls.
The organisation has also said that registering itself as a party would make it easier to get its candidates in elections, because official party status means candidates do not require support from an electors' association.
Additionally, each candidate is required to garner the support of 100 people before being able to establish a voters' association.
