Finland's president and Prime Minister (PM) called for the country to apply for NATO membership "without delay". It comes amid a surge in public support for NATO membership following Russia's invasion of Ukraine.
Finland shares a 1,300-km (810-mile) border with Russia. Until now, it has stayed out of NATO to avoid antagonising its eastern neighbour. Russia has said it will be forced to take "retaliatory steps" over its neighbour Finland's move to join NATO.
