Sweden has formally joined Nato as the 32nd member of the transatlantic military alliance, ending decades of post-Second World War neutrality as concerns about Russian aggression have spiked after the invasion of Ukraine.

Swedish Prime Minister Ulf Kristersson and Secretary of State Antony Blinken presided at a ceremony in which Sweden’s “instrument of accession” to the alliance was officially deposited at the State Department.
