Finland’s president and government declared on Sunday that the Nordic country intended to seek for NATO membership, paving the path for the 30-nation Western military alliance to expand amid Russia’s conflict in Ukraine.

The announcement was made at a joint press conference held by President Sauli Niinisto and Prime Minister Sanna Marin at the Presidential Palace in Helsinki.

The decision is expected to be approved by the Finnish Parliament in the next days, but it is only a formality.

Following that, a formal membership application will be filed to NATO headquarters in Brussels, most likely next week.

Russia’s military push in Ukraine looks to be weakening, according to a senior NATO official, who expressed faith that Kyiv will win the battle.

In the face of Russian threats, top NATO ambassadors are gathering in Berlin on Sunday to consider providing additional help to Ukraine and moves by Finland, Sweden, and others to join the western alliance.
