AUKUS

Lord Browne of Ladyton Excerpts

Thursday 16th September 2021 Lords Chamber

[Baroness Goldie (Con)]

I say to my noble friend that we see this as a partnership among three important global players. It is a partnership with important and broad security objectives but its immediate raison d’être, as driven by Australia, is to seek help in being supplied with nuclear-powered submarines. That is the first focus of the partnership; it is therefore not something that it would be appropriate for France to be involved in.

On our broader relationship with France, I hope that my noble friend was assured by what I said in my earlier remarks. France is related to us and our defence relationships in a number of ways, not least on our bilateral front but also through NATO. There is a strong relationship there that we want to nurture and sustain.

My noble friend asked when the partnership will be operational. This is a technically challenging proposition. The first phrase will happen over the next 18 months and will involve a tripartite, or trilateral, discussion among the three parties to the agreement as they work out what is possible and how matters might be taken forward.

My noble friend also asked about command. This is not a military operation; it is an alliance, first of all, to help with the specific project of building and delivering nuclear-powered submarines. The submarines will be under the command of Australia, and it will have autonomy of operation over them.

[Lord Browne of Ladyton (Lab)]

My Lords, like the noble Lord, Lord Ricketts, I have had insufficient time to get my head around the implications of what I consider to be quite a momentous announcement. I assume that the Government worried those implications to death before they agreed to join, so I have two questions.

First, assuming that the method of propulsion for these boats will use highly enriched uranium—a fissile, weapons-grade material—and the safeguarding of this material will be outside the IAEA structure, who will take responsibility for that safeguarding? What steps can we ensure are taken, and how will they be reported?

Secondly, this is the first time in history that a non-nuclear arms state will acquire a nuclear submarine. What assessment have the Government and their allies made of the sort of signal this sends to our adversaries that are nuclear arms states? Have we considered that this will be interpreted by them as permission to equip all their allies and friends with nuclear submarines? If so, this has momentous consequences for the proliferation of these materials and weapons in the world.

[Baroness Goldie (Con)]

I thank the noble Lord. He used an interesting adjective in relation to this agreement; he described it as “momentous”, which I think is an accurate and apposite assessment. His concern about nuclear materials was basically whether we have asked our URENCO partners for permission. In the next 18 months, we will consider a wide range of technical, legal and practical issues for this project and do not want to pre-empt those findings. I reassure the noble Lord that the usual high standards of security will be maintained. The UK’s nuclear enterprise has more than 60 years of experience of delivering world-class, nuclear-powered submarine capabilities safely.

On the interesting issue of the IAEA, we have spoken to the IAEA director-general and will keep in close touch. As the noble Lord indicated, it does not have competence for nuclear defence issues, but we will engage with it as appropriate during the consultation period to ensure that we are fulfilling our obligations and to give absolute confidence that no HEU will be diverted for weapons purposes.
