Responding to Montenegro’s accession to NATO, the Foreign Secretary Boris Johnson said:‪

NATO is the bedrock of our collective security and I welcome Montenegro as the 29th member. The UK has long been a firm supporter of Montenegro’s accession, as well as its commitment to reform and progress. I congratulate them on a historic step forward.

Montenegro now takes on both the benefits and responsibilities of NATO membership and collective defence. We look forward to building on our close relationship for the defence and security of our citizens.
