Lords urge AUKUS expansion to Canada, Japan, South Korea
In a recent House of Lords debate, members discussed amendments to the UK-US Mutual Defence Agreement (MDA) and advocated for expanding the AUKUS alliance—a trilateral security partnership with Australia and the US—to include Canada, Japan, and South Korea.Led by Lord Goldsmith, the debate focused on the importance of parliamentary scrutiny and enhancing cooperation in nuclear defence.
Established in 1958, the MDA is a key agreement underpinning nuclear cooperation between the UK and the US, allowing for the exchange of nuclear materials and technology essential to the UK’s independent deterrent. The latest amendment removes the need for a 10-year renewal, creating an “evergreen” agreement. While many viewed this continuity as strengthening the UK’s deterrent, some raised concerns over reduced parliamentary oversight.
Lord Goldsmith highlighted the International Agreements Committee’s recommendation that, in place of regular renewals, the government should commit to providing a report to Parliament on the MDA every decade. He remarked that while the change provides valuable continuity, it reduces Parliament’s role in monitoring developments in nuclear defence.
“This is yet another example of the shortcomings of the CRaG regime,” he noted, referring to the Constitutional Reform and Governance Act’s (CRaG) limited 21-day scrutiny period.
In contrast, Lord Verdirame supported the amendment, arguing that
“an indefinite agreement is appropriate…given the strategic importance of our alliance with the United States.” He added that the amended terms align well with the MDA’s legal framework, which already requires mutual consent for termination.
Lord Hannay described the CRaG process as
“absurdly short,” especially when compared to the extended review period in the US Congress. Many members called for a more comprehensive scrutiny process for treaties like the MDA.
The debate also covered AUKUS, with Lord Udny-Lister describing it as a
“key pillar” of the UK’s Indo-Pacific defence strategy. The agreement, which provides Australia with nuclear-powered submarines, also facilitates cooperation on advanced military technologies such as AI, quantum computing, and hypersonics. Lord Udny-Lister noted that AUKUS not only bolsters UK security but also strengthens
“opportunities for technological advancement and military exports, particularly in the Indo-Pacific.”
Several members called for an expansion of AUKUS to include Canada, Japan, and South Korea. Lord Hannan argued that this could create a broader, democratic alliance to counterbalance
“rival models” from authoritarian states. Echoing this, Lord Bilimoria noted that
“expanding AUKUS would help reinforce international security and provide deeper technological and economic ties among allies.”
Economic opportunities were also highlighted, with many members noting AUKUS’s potential to benefit the UK’s defence industries. Lord Bilimoria stated that
“the UK’s defence industries…stand to benefit significantly,” adding that AUKUS would create demand for
“highly skilled jobs and manufacturing.” However, Baroness Bennett raised environmental and fiscal concerns, questioning whether this nuclear-based strategy aligns with modern defence requirements.
