Turkey's parliament scheduled a vote on the Nordic country's bid to become the 31st member of the Western defence alliance for 2:00 pm (1100 GMT).

Ratification is all but certain after President Recep Tayyip Erdogan ended months of negotiations and blessed Finland's candidacy earlier this month.

Erdogan controls parliament through an alliance with a right-wing party. Most opposition lawmakers also support the bid.

Turkey's ratification will leave Finland -- a country with a 1,300-kilometre (800-mile) border with Russia -- with only a few technical steps before formally joining the bloc.

Finland and its neighbour Sweden ended decades of military non-alignment and decided to join the alliance last May.

Their applications were accepted at a June 2022 NATO summit but the bids still needed to be ratified by all alliance member parliaments -- a process that stalled once it reached Turkey and Hungary.

Erdogan put up stiff resistance to Sweden's candidacy because of a series of long-standing disputes.

A spokesman for Hungarian Prime Minister Viktor Orban on Wednesday called on Sweden to "clear the air" and address "an ample amount of grievances" for parliament to ratify its bid.

Sweden still hopes to join the alliance in time for a July summit in Vilnius.

Most analysts believe that Turkey will only vote on its candidacy after the country's May general election.
