The majority of MPs voted to maintain the UK's minimum strategic nuclear deterrent beyond the life of the existing system.

MPs were considering the following motion:

  • That this House
  • supports the Government's decisions, as set out in the White Paper The Future of the United Kingdom's Nuclear Deterrent (Cm 6994), to take the steps necessary to maintain the UK's minimum strategic nuclear deterrent beyond the life of the existing system and to take further steps towards meeting the UK's disarmament responsibilities under Article VI of the Non-Proliferation Treaty.

In this vote majority of MPs voted against changing the above motion supporting the Government's nuclear weapons policy to one which read.[1]

  • This House
  • notes the Government's decision, as set out in the White Paper The Future of the United Kingdom's Nuclear Deterrent (Cm 6994),[2] to take the steps necessary to maintain the UK minimum strategic nuclear deterrent beyond the life of the existing system and to take further steps towards meeting the United Kingdom's disarmament responsibilities under Article VI of the Non-Proliferation Treaty,[3]
  • but believes that the case is not yet proven and remains unconvinced of the need for an early decision.

The Government's original motion, still intact, was subsequently voted for by a majority of MPs.[4]

Seven MPs voted inconsistently between the two motions.[5]

The majority of MPs voted to maintain the UK's minimum strategic nuclear deterrent beyond the life of the existing system.

The majority of MPs voted for the motion:[1]

  • This House

This followed a previous vote against asserting that the case was "not yet proven",[4] and was recognized as Parliamentary authorization for the development of a new generation of submarines and launch vehicles for the deployment of ballistic nuclear weapons against targets unknown.[5][6]

How the number is calculated

The MP's votes count towards a weighted average where the most important votes get 50 points, less important votes get 10 points, and less important votes for which the MP was absent get 2 points. In important votes the MP gets awarded the full 50 points for voting the same as the policy, no points for voting against the policy, and 25 points for not voting. In less important votes, the MP gets 10 points for voting with the policy, no points for voting against, and 1 (out of 2) if absent.

Questions about this formula can be discussed on the forum.

*Pressure of other work means MPs or Lords are not always available to vote – it does not always indicate they have abstained. Therefore, being absent on a less important vote makes a disproportionatly small difference.
