Finland’s president confirms country will apply to join Nato in historic shift; ‘mistake’ says Putin
- The monumental decision was prompted by Russia’s invasion of Ukraine; the attack shifted popular opinion overnight, kicking off a process to join the alliance
- Sweden is also expected to follow suit as public support for membership has grown amid security concerns

Finland’s President Sauli Niinisto confirmed on Sunday that his country would apply for membership of the Nato military alliance, in a historic policy shift prompted by Russia’s invasion of Ukraine.
Moscow, which shares a 1,300km (800 mile) border with Finland, has said it would be a mistake for Helsinki to join the transatlantic alliance and that it would harm bilateral ties.
Sweden is also expected to follow suit as public support for membership has grown amid security concerns.
Sunday’s announcement comes after Niinisto and Prime Minister Sanna Marin said on Thursday they both favoured Nato (North Atlantic Treaty Organisation) membership, giving a green light for the country to apply.
“Today, we, the president and the government’s foreign policy committee, have together decided that Finland … will apply for Nato membership,” Niinisto told reporters in the presidential palace in Helsinki.
Niinisto called Russian President Vladimir Putin on Saturday to tell him of Finland’s plans to join the alliance. Putin said such a move would hurt Russian-Finnish relations.
