Hungary's parliament will meet on Monday at the request of opposition parties with the ratification of Sweden's NATO bid expected to be on the agenda, a document on parliament's website showed on Thursday, APA reports citing Reuters.
But it was not clear if ruling Fidesz party lawmakers, who hold a large majority in parliament, would attend the extraordinary meeting, meaning it would not be able to ratify Sweden's bid.
Hungary is the only NATO member that has not approved Sweden's application to join the alliance.
Türkiye's President Tayyip Erdogan signed Sweden's accession documents in late January, leaving Hungary as the last hold-out.
Earlier on Thursday, Orban's chief of staff said Fidesz lawmakers wanted to see steps from Sweden to strengthen confidence before they can approve its NATO bid. He did not elaborate on what those steps were.
Parliament is scheduled to reconvene for a normal session after its winter break in late February.
