The Official Gazette's publication of the law on Sweden's accession to the alliance, which the Turkish parliament approved on Tuesday, ends a nearly two-year saga that tested Ankara's relations with its Western allies.

Finland became the 31st nation of the alliance last April.

Swedish Prime Minister Ulf Kristersson said Thursday he was ready to meet his Hungarian counterpart Viktor Orban to help pave the way for Budapest's quick approval of the bid.

NATO membership applications require unanimous ratifications by all alliance members.
