NATO secretary general Jens Stoltenberg has confirmed that an independent Scotland would have to leave the alliance.
Updated 29th December 2019.
“If it happens, then the UK will continue as a member of NATO but a new independent state has to apply for membership and then it is up to 28 allies to decide whether we have a new member.
All decisions in NATO are taken by consensus, so we need the consensus of all allies.
By leaving the UK it will also be leaving Nato, but of course it is possible to apply for membership and then the allies would then decide whether the independent state would become a member of NATO.”
It is understood that many believe Scotland would likely face the issue of having its entry challenged by Spain which is cautious of encouraging break-away states due to the independence movement in its Catalonia region. However in light of Spain’s recent statements regarding their acceptance of Scotland’s entry to the European Union, this is unlikely to be the case.
An independent Scotland would meet most the entry requirements of the alliance however it may not be able to join for many years if approved as the entry process for the alliance is lengthy.
