Portugal
Portugal boycotted the TPNW negotiations in 2017 and has consistently voted against the annual UN General Assembly resolutions on the Treaty, including in 2023. Portugal may sign and ratify or accede to the TPNW, but will have to make changes to its policies and practices to become compliant.

Latest developments
In the First Committee of the UN General Assembly in October 2023, Portugal expressed concern that the nuclear disarmament and non-proliferation architecture is eroding. ‘The shadows cast by nuclear weapons challenge international law, the norms, rules and principles of an international order based on responsible behaviour, and multilateral cooperation founded on the United Nations Charter,’ it said.1
The former Portuguese defence minister Nuno Severiano Teixeira was among the signatories to an open letter in September 2020 calling on current leaders in umbrella states to 'show courage and boldness' and join the TPNW.2
Recommendations
-
Portugal should renounce the possession and potential use of nuclear weapons on its behalf, and ensure that nuclear weapons do not have a role in its defence posture.
-
Portugal should comply with its existing obligation under Article VI of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and pursue negotiations in good faith on nuclear disarmament.
-
Portugal should urgently adhere to the TPNW. Until it is in a position to do so, it should welcome the TPNW as a valuable component in the global disarmament and non-proliferation architecture, work with the Treaty's states parties on practical steps towards disarmament, and attend the meetings of states parties as an observer.
