Watch as Turkey’s parliament voted on Sweden’s Nato accession on Tuesday, 23 January.
The Scandinavian nation’s bid was ratified after 20 months of delay.
Sweden, alongside Finland, asked to join the intergovernmental military alliance of 31 member states in 2022.
Its accession was delayed - Turkey raised objections over what it said was the two countries’ protection of groups that Ankara deems terrorists.
Ankara asked Stockholm to toughen its stance on local members of the Kurdistan Workers’ Party (PKK), which the EU and US also describe as a terrorist group.
Sweden introduced a new anti-terrorism bill that makes being a member of a terrorist organisation illegal.
