The hon. Gentleman is absolutely right. Of course, the last Labour Government held votes in this House on the retention of the nuclear deterrent. It is a great pity that there are Members on the Labour Front Bench who fail to see the necessity of the nuclear deterrent, given that in the past the Labour party has put the British national interest first when looking at the issue.
I want to set out for the House why our nuclear deterrent remains as necessary and essential today as it was when we first established it. The nuclear threat has not gone away; if anything, it has increased.
First, there is the threat from existing nuclear states such as Russia. We know that President Putin is upgrading his nuclear forces. In the past two years, there has been a disturbing increase in both Russian rhetoric about the use of nuclear weapons and the frequency of snap nuclear exercises. As we have seen with the illegal annexation of Crimea, there is no doubt about President Putin’s willingness to undermine the rules-based international system in order to advance his own interests. He has already threatened to base nuclear forces in Crimea and in Kaliningrad, the Russian enclave on the Baltic sea that neighbours Poland and Lithuania.
Secondly, there is the threat from countries that wish to acquire nuclear capabilities illegally. North Korea has stated a clear intent to develop and deploy a nuclear weapon, and it continues to work towards that goal, in flagrant violation of a series of United Nations Security Council resolutions.
