MSP Rona Mackay has formally supported the EU Treaty on the Prohibition of Nuclear Weapons.
On Thursday November 23, the Strathkelvin and Bearsden MSP signed the ICAN Parliamentary Pledge.
The pledge commits parliamentarians to help ratify the EU treaty in their respective nations.
ICAN, an international civil society group against nuclear weapons, has instigated the pledge signing for parliamentarians from across the world.
Ms Mackay said: “I was honoured to sign this important pledge of support for the Ban Treaty.
“This change in International Law will usher in a necessary shift in bringing human rights to the forefront of the nuclear disarmament debate.
“Nuclear weapons not only kill hundreds of thousands of civilians but are also lived-through. They have lasting detrimental effects on families and communities of survivors (Hibakusha), many of whom saw the devastation first hand.
“I urge the UK Government to sign the UN Ban Treaty so they can stand with the majority of states in the world who have already taken this step.”
