The process of admission of Finland and Sweden to NATO is proceeding at an unprecedented speed, but the date of their accession will depend only on the countries' ratification of the accession protocol, said NATO Secretary General Jens Stoltenberg upon arrival at the summit.

The leaders will make a historic decision to invite Finland and Sweden to become NATO members based on an agreement between Sweden, Finland and Turkey, NATO leader noted.

He added that the leaders will issue invitations to these countries at the summit, which means that only a few weeks have passed between the application and the invitation, this is unprecedentedly fast.

After the invitation, the process of ratification by the parliaments of all 30 countries will begin, and this will take some time.
