Sweden’s Prime Minister Magdalena Andersson has said her country will join Finland in seeking Nato membership following Russia’s invasion of Ukraine.

       The historic shift, if agreed by Nato members, would end more than 200 years of military non-alignment.

       The Swedish leader said she expected the application to take no more than a year.

       “We will inform Nato that we want to become a member of the alliance,” Prime Minister Magdalena Andersson said.

       The announcement came after a debate in parliament on Monday which showed is huge support among MPs for joining Nato.

       Out of Sweden’s eight parties, only two smaller left-leaning parties opposed it.

       Twenty four hours earlier, the Swedish Social Democrats broke with the party’s long-standing position that Stockholm must remain non-aligned, paving the way for a clear majority for Nato membership in parliament.

       The move comes after neighbouring Finland announced it too would seek to join the 30-country alliance.

       Public opinion in both countries was firmly against joining Nato before the Russian invasion of Ukraine on February 24, but support for membership surged quickly after that.

       International reaction was swift, with France and Denmark backing Sweden’s decision.

       Foreign minister Ann Linde wrote on Twitter: “The Swedish government’s intent is to apply for NATO membership. A historic day for Sweden. With a broad support from political parties in the parliament, the conclusion is that Sweden will stand stronger together with allies in NATO.”

       Once a regional military power, Sweden has avoided military alliances since the end of the Napoleonic Wars.

       Like Finland it remained neutral throughout the Cold War, but formed closer relations with Nato after the 1991 Soviet collapse.

       After the Russian invasion of Ukraine, the governments in Finland and Sweden responded by swiftly initiating discussions across political parties about Nato membership and reaching out to the US, Britain, Germany and other Nato countries for their support.

       The Kremlin, however, has repeatedly warned the move would have destabilising consequences for security in Europe.

       Mr Putin said on Monday that Moscow “does not have a problem” with Sweden or Finland as they apply for Nato membership, but that “the expansion of military infrastructure on to this territory will of course give rise to our reaction in response”.
