Türkiye's parliament is widely expected to approve Sweden's NATO membership bid on Tuesday, clearing the biggest remaining hurdle to expanding the Western military alliance after 20 months of delays, Paralel.Az reports citing Reuters.

Türkiye's general assembly, where President Tayyip Erdogan's ruling alliance holds a majority, is set to vote on the application that Sweden first made in 2022.

Once parliament has ratified the move, Erdogan would be expected to sign it into law within days, leaving Hungary as the only member state not to have approved Sweden's accession.

Hungary had pledged not to be the last ally to ratify, but its parliament is in recess till around mid-February. Prime Minister Viktor Orban said on Tuesday he invited his Swedish counterpart to visit and negotiate his country joining the bloc.

"I don't see any reason to negotiate in the current situation, though ... we can have a dialogue and continue to discuss questions," Swedish Foreign Minister Tobias Billstrom told Swedish news agency TT.

Sweden's government had no comment on Türkiye's parliamentary process.
