On Sunday afternoon, President Sauli Niinistö and Prime Minister Sanna Marin (SDP) announced that Finland will seek to join the North Atlantic Treaty Organisation (Nato).
Niinistö formally made the announcement in Finnish, Swedish and English, saying that Finland was entering a new era.
In the meeting, Niinistö and the Ministerial Committee agreed that Finland would apply for membership after Parliament has been heard.
In a joint statement last Thursday, Niinistö and Marin said that Finland should apply for Nato membership as a matter of urgency.
According to Niinistö, Putin stated that in his view Finland was "not under any threat" and that joining Nato was "a mistake".
He described Putin's reaction to the decision as surprisingly muted considering previous Russian threats over Finnish moves toward membership.
Police estimated that 300-500 people took part in the demonstration under the slogan "No to Nato, yes to peace". »
