Non-proliferation Treaty: 50th Anniversary Review

Debate between Graham Stuart and Peter Dowd

Wednesday 13th July 2022 Westminster Hall

[The Minister of State, Foreign, Commonwealth and Development Office (Graham Stuart)]

It is a pleasure to serve under your chairmanship, Mr Dowd. I am grateful to the hon. Member for Brentford and Isleworth (Ruth Cadbury) for securing the debate ahead of the NPT review conference in August, and to the hon. Member for Brighton, Pavilion (Caroline Lucas) for stepping in and leading it.

I completely agree with the shadow Minister, the hon. Member for Leeds North East (Fabian Hamilton) on the quality of the debate that we have enjoyed this afternoon. I will try to respond to as many of the points raised as possible in the perhaps eight minutes before we vote.

We had a mention of RAF Lakenheath. It remains long-standing UK and NATO policy neither to confirm nor deny the presence of nuclear weapons at a given location. The UK does not have a policy of no first use because—this goes to the heart of much of what we are discussing—the credibility of the deterrent rests on the conviction that we would bring all means to bear to ensure the security of the UK and our allies.

The hon. Member for Brighton, Pavilion referred to the treaty on the prohibition of nuclear weapons. The TPNW fails to address the obstacles that must be overcome to achieve lasting global disarmament and offers no solutions to the challenges posed by what is, as hon. Members suggested and with which I agree, a deteriorating security environment. The TPNW will not lead us closer to a world without nuclear weapons and risks creating division within the international community, at a time when we need to focus on building consensus and strengthening the NPT to make progress on disarmament together.

What I have picked up, enjoyed and appreciated in the debate—the right hon. Member for Islington North (Jeremy Corbyn) was particularly fluent on the point, but hon. Members across the Chamber picked it up—is the recognition of the importance of the NPT. It is a remarkably successful treaty. Over the last 52 years, the NPT has been the cornerstone of global nuclear security and civil nuclear prosperity.

In 1960, as the right hon. Member for Islington North mentioned, President Kennedy predicted that there could be up to 20 nations with nuclear weapons as soon as 1964. Yet today the number of nuclear-armed states remains in single figures, thanks to the NPT. It is important that we recognise that and cement that progress, although I recognise people will want other initiatives. The NPT has extended access to the peaceful use of nuclear energy. It has prevented the proliferation of nuclear weapons. It has provided a framework for significant levels of disarmament since the cold war peak. It has been remarkably successful.

Now, after two years of delay, we are delighted that states will be able to come together next month in New York to review implementation and take forward the objectives of the treaty. The UK remains committed to full implementation of the NPT in all its aspects. We are a nuclear weapons state that takes its responsibilities seriously. We are committed to the long-term goal of a world without nuclear weapons, where all states share in the peaceful uses of nuclear technologies.

At the review conference, the UK will work constructively with states parties for a successful outcome. We will mark the progress of the past 50 years and call on all states to reaffirm their commitment to the three pillars of the treaty—disarmament, non-proliferation and peaceful uses of nuclear technology.

Celebrating success does not mean ignoring reality. Since the last conference in 2015, we have seen a significant deterioration in the security environment and the treaty faces a number of challenges. We have previously identified risks to the UK from major nuclear-armed states and emerging nuclear states. Those risks have not gone away, and some states are now significantly increasing and diversifying their nuclear arsenals. They are investing in novel nuclear technologies and developing new warfighting nuclear systems, which they are integrating into their military strategies and doctrines, and into their political rhetoric, to seek to coerce others. The increase in global competition and the proliferation of potentially disruptive technologies mean there are new threats to strategic stability.

Russia’s illegal and unprovoked invasion of Ukraine, which the right hon. Member for Islington North rightly and fully condemned, is a dramatic demonstration of the risks we face. We do not underestimate the challenges. They make strengthening the NPT more important. The treaty is not an academic document. It must live in the real world and adapt to address modern challenges. We believe the NPT provides the only credible route to nuclear disarmament.

The UK Government are proud of our contribution to the NPT’s success and of our own track record. We set out the steps we have taken since 2015 in the UK’s national report, published last November. I refer those asking for clarity on the UK’s views and objectives to that report. It sets them out. Our views have not changed since that report. If people have already read it, they should look again. We share the aspirations of all states parties to the NPT for a world without nuclear weapons. Disarmament cannot be done unilaterally or in a single leap. It requires a series of incremental, mutually reinforcing steps.

Building such a framework requires the active participation of the entire international community. Rallying their many disparate interests presents a huge diplomatic challenge, but it is one in which the United Kingdom has already played a significant role. We have pioneered work in nuclear disarmament verification, championed transparency and advanced understanding on irreversibility. In December we published a food for thought paper, outlining one vision for how to get to a world without nuclear weapons in support of the forthcoming review conference that hon. Members have mentioned.

We have pressed for significant steps towards multilateral disarmament, including the entry into force of the comprehensive test ban treaty and successful negotiations on a fissile material cut-off treaty. It is the comprehensive test ban treaty that deals with the testing issues, which have been referred to by hon. Members, as opposed to the NPT. We possess the smallest stockpile. That is worth noting, given the impression that in some way the UK has not been stepping up: we possess the smallest stockpile of any of the nuclear weapon states recognised by the NPT, and we are the only one to maintain a single delivery system—

[Peter Dowd (in the Chair)]

Order. There is a Division in the House.

[Peter Dowd (in the Chair)]

Order. I apologise to the Minister for rudely interrupting him earlier on. He can carry on where he left off.

[Graham Stuart]

Thank you, Mr Dowd. It is a pleasure to be back. I am grateful to Members for returning to the debate.

We remain committed to our article 6 obligation to pursue negotiations in good faith on effective measures relating to nuclear disarmament. Reducing the risk of nuclear conflict remains a priority and we believe that short-term progress, in line with many of the contributions we have had, is achievable. We should seek to foster dialogue, which many Members have mentioned, both among states possessing nuclear weapons and between states possessing nuclear weapons and non-nuclear weapon states in order to increase understanding and reduce the risk of misinterpretation and miscalculation.

Although we recognise that work on risk reduction does not replace disarmament obligations, we see it as a complementary and necessary step to reduce the risk of nuclear conflict and enhance mutual trust and security. We will continue to work with international partners, civil society and academia to build mutual trust and create the environment for further progress on disarmament.

The UK works to limit the spread of nuclear weapons. We have sought to strengthen the international nuclear safeguard system and the International Atomic Energy Agency through our diplomatic efforts and through direct assistance from our nuclear safeguards programme. We will encourage all states that have not yet done so to sign, ratify and implement safeguards agreements. We will promote the ratification of security conventions and seek universal commitment to the additional protocol and a comprehensive safeguards agreement, which together provide credible assurances of the absence of undeclared nuclear activities and will strengthen the non-proliferation architecture. Nevertheless, the UK recognises that significant regional risks remain, particularly from Iran and North Korea. They have been highlighted in the debate. We are working hard to combat the risk of proliferation and remain firmly committed to ensuring coherence to the NPT and the IAEA safeguards regime to ensure global safety and stability.

Finally, the UK has encouraged and will continue to encourage the development and exchange of peaceful nuclear technologies, enabled by the NPT. Nuclear technologies have a critical part to play in tackling climate change, for instance, not only in helping to achieve net zero, but also through nuclear applications such as helping to improve food security and agricultural resilience. The technologies can help countries to adapt and become more resilient to climate change. They are also vital to global health, as they are used to treat cancer and prevent the spread of insect-borne disease. We want the review conference to highlight the significant global contribution that the peaceful use of nuclear technology makes to improving people’s lives and advancing progress to the UN sustainable development goals.
