The Hungarian approval of Swedish entry into NATO has been delayed. But when Turkey gave the green light to Sweden on Monday, Hungary's foreign minister announced that the approval is now "just a technicality".
Notification within a week
A decision in the Hungarian Parliament is still required for Swedish membership. A vote can either take place when Parliament reconvenes at the end of September or if the President calls an extraordinary session, which is not unusual in Hungary.
"We will probably know more within about a week. The Hungarian government has announced that they will meet for a three-day meeting, after the NATO meeting in Vilnius.
The expert: Doubtful if Hungary helped Turkey
Hungary has not presented any concrete reason for the delay in approving Sweden. Rudolf Berkes believes that it is a matter of hoping for financial and political support from Turkey.
"But one can question whether Hungary has really succeeded in supporting Turkey. Turkey has negotiated successfully on its own.
Turkey also does not seem to have discussed its acceptance of Sweden with Hungary.
"It is quite embarrassing that Erdogan has not discussed the issue with Hungary if it is now the case that Hungary's actions are because it wants to support Turkey.
"No one here wanted to mention Hungary"
Rudolf Berkes is one of the participants at the NATO public forum, the open part of the meeting in Vilnius.
"It was clear here that no one wanted to mention Hungary when talking about Sweden. Everyone was talking about Turkey and about the negotiations that have been completed.
According to Berkes, NATO colleagues have not considered Hungary important on the issue of Sweden.
"Probably because they understood that Hungary's actions are only a negotiation game and that Hungary has nothing concrete against Sweden, on the contrary, they believe that Sweden can strengthen NATO.
