Parliamentarians for Nuclear Non-Proliferation and Disarmament (PNND) is a global network of over 700 parliamentarians from more than 75 countries working to prevent nuclear proliferation. Membership is open to current members of legislatures and parliaments at state, federal, national and regional levels. In October 2011, David Coltart was elected co-president of PNND at the Kursaal Convention Centre in Bern, Switzerland.[1]
