Finland’s President and Government announced Sunday that the Nordic country intends apply for membership in NATO, paving the way for the 30-member Western military alliance to expand amid Russia’s war in Ukraine.

President Sauli Niinisto and Prime Minister Sanna Marin made the announcement at a joint news conference at the Presidential Palace in Helsinki.

The Finnish Parliament is expected to endorse the decision in coming days, but it is considered a formality.

A formal membership application will then be submitted to NATO headquarters in Brussels, most likely at the some point next week.
