Abolition 2000 is a worldwide network working for a global treaty to eliminate nuclear weapons.
On 4th May, there was a debate on the replacement of Trident (British nuclear weapon system) in the Scottish Parliament.

Note: the Scottish Parliament does not have responsibility for Defence or Foreign affairs, it is a "reserved" issue, meaning that the British Parliament retains responisbility.

(Full text of the debate, Scottish Parliament website)

The substantive motion, introduced by the Green party:

That the Parliament believes that the United Kingdom should not seek to replace the Trident nuclear missile system; notes that in 2005 the UK Government reaffirmed its commitment to all its obligations under the nuclear Non-Proliferation Treaty 1967 (NPT), including its legally binding obligation to negotiate nuclear disarmament in good faith; agrees with the legal opinion of Rabinder Singh QC and Professor Christine Chinkin of Matrix Chambers on 19 December 2005 that any replacement of the Trident system would constitute a material breach of Article VI of the NPT, and calls on the Scottish Executive to seek an early assurance from the UK Government that it will fully comply with our legal obligations in respect of the NPT and that it will not seek to replace the Trident nuclear missile system with another weapon system of mass destruction.

Votes: For 38, Against 73, Abstentions 4.

Amendments by Labour (calling for debate on the issue "considering all possible options including non-replacement") the Liberal Democrats (calling for the retention of Trident until there was significant international movement on nuclear disarmament) the Conservatives (calling for the retention of nuclear weapons, within a NATO context) and the Scottish Nationalists (calling for an independent Scotland as the quickest way to nuclear disarmament) were all defeated by various margins.
