Ukraine War: Finland to decide on Nato membership in weeks says PM Marin

Finnish Prime Minister Sanna Marin says her country will decide on whether to apply to join Nato "within weeks".

She said she saw no reason to delay the decision, at a joint news conference alongside Sweden's prime minister.

Her comments coincided with a report to the Finnish parliament that warned membership of the bloc could result in "increased tensions on the border between Finland and Russia".

Moscow has warned Finland and Sweden against joining Nato in recent weeks.

Finland and Sweden are militarily non-aligned but Russia's invasion of Ukraine has prompted increasing public support to become members of the Western defensive alliance. Swedish leader Magdalena Andersson told reporters that the same "very serious analysis" was taking place as in Finland and she saw no point in delaying it.

Swedish newspaper Svenska Dagbladet reported on Wednesday that Ms Andersson was aiming to apply for Nato membership in time for a Nato summit in late June.

Finland shares a 1,340km (830 miles) border with Russia, and Kremlin spokesman Dmitry Peskov has stressed that Moscow would have to "rebalance the situation" with its own measures if the Nato bid went ahead.

"I won't give any kind of timetable when we will make our decisions, but I think it will happen quite fast," said Ms Marin. She pointed out that Nato membership offered Finland the security guarantee of Article Five, whereby an attack on one member is viewed as an attack on all.

While the two leaders met in Stockholm, Finland's security review was being launched in Helsinki. Foreign Minister Pekka Haavisto said Russia's war had changed the security environment in Europe and forced the review of Finnish defence policy.

It also noted that were Finland to join the bloc it would be forced to spend up to 1.5% more of its budget on defence, but added that membership of the alliance would offer the country a greater capacity defend itself. Finland has already announced a 40% increase in its defence budget by 2026.

Any potential application would also welcome a bid by neighbouring Sweden to seek membership of the bloc, it added.

The Finnish government emphasised that the report "does not include any conclusions or present new security policy guidelines" and said that no decisions would be made before parliament had debated its findings.

Ms Marin told reporters that "all the parliamentary groups, government and also the president will have the possibility to make the decisions within upcoming weeks".

Defence Minister Antti Kaikkonen said the military situation remained calm but cautioned that the army must be ready for possible changes. The prime minister warned earlier that Finland had to be prepared for a Russian attack during any potential Nato evaluation process.

There have been reports that Moscow has started to move military equipment towards the Russian-Finnish border, although US officials said they had seen nothing to confirm that.

Finland has maintained a policy of military neutrality designed to avoid confrontation with Russia since Nato was formed in 1949. In 1939, Finland fought off an invasion from the Soviet Union in what became known as the Winter War, but ended up ceding its eastern province of Karelia.

Ms Marin's ruling Social Democratic party has traditionally supported the policy of non-alignment and she reiterated it as recently as March. But recent opinion polls show that public support for joining Nato has climbed from 28% in February to 62% last month.

Finland retains a large standing military of around 21,500 troops and has the capacity to call up over 200,000 reservists in the event of war.
