The next step is a full parliament vote that is also expected to pass, likely to be held within weeks. Erdogan would then sign it into law, concluding a process that frustrated some of Ankara's allies and tested its Western ties.

Sweden and Finland asked to join NATO last year in the face of Russia's invasion of Ukraine. While Ankara ratified Finland, it has raised objections to Sweden's bid over what it said was Stockholm's protection of groups that Ankara deems terrorists.

While NATO member Hungary has also not ratified Sweden's membership, Turkey is seen as the main roadblock to adding the Scandinavian nation to the military alliance and bolstering its defences in the Baltic Sea region.
