Anne-Marie Trevelyan – 2022 Speech on the Sovereignty of the British Indian Ocean Territory

The speech made by Anne-Marie Trevelyan, the Minister of State at the Foreign Office, in Westminster Hall, the House of Commons, on 7 December 2022.

I thank my hon. Friend the Member for Shrewsbury and Atcham (Daniel Kawczynski) for securing this important debate. Hon. Members have all highlighted the UK’s recently opened negotiations with Mauritius on the exercise of sovereignty over the British Indian Ocean Territory, also known as the Chagos archipelago. The Foreign Secretary announced the beginning of the negotiations on 3 November. That followed discussions with Mauritius at the Commonwealth Heads of Government meeting in June and at the UN General Assembly in September.

I can confirm that negotiations have formally begun. Officials from the United Kingdom and Mauritius met on 23 and 24 November, and they had constructive discussions. They will meet again shortly to continue those discussions and negotiations. Hon. Members will appreciate that we will not provide any detail on the content of ongoing discussions or speculate on the outcome. However, I commit to and reassure Members that we will keep them and Parliament informed at key junctures through the process.

The UK and Mauritius intend to secure an agreement on the basis of international law to resolve all outstanding issues. I anticipate any agreement will be subject to parliamentary scrutiny under the Constitutional Reform and Governance Act 2010 in the usual way. Let me be clear that both the UK and Mauritius have reiterated that any agreement between us will ensure the continued effective operation of the joint UK-United States defence facility on Diego Garcia. For more than 40 years, this joint base has contributed significantly to regional and global security. It is the result of a uniquely close and active defence and security partnership between two longstanding allies.

The base helps the UK, US and other allies and partners to combat some of the most challenging threats, including from terrorism, organised crime and instability. The base is well positioned as a key enabler for maritime security, including the protection of regional shipping lanes from threats such as piracy. Diego Garcia also plays a key role in humanitarian efforts, ready for a rapid response in times of crisis or disaster in the region. That includes during the 2004 earthquake and tsunami in the Indian ocean, the 2011 earthquake and tsunami in Japan and the 2013 typhoon in the Philippines. The base plays an important part in assisting the operation of the global positioning system, GPS, and helping the international space station to avoid space debris and prevent satellite collisions.

We are alive to concerns about influence from malign actors in the Indian ocean. My right hon. Friend the Foreign Secretary acknowledged these concerns when he gave evidence to the Foreign Affairs Committee on 14 November. He assured the Committee that this is an issue we take very seriously and that we will ensure it is at the heart of our position during the sovereignty negotiations with Mauritius.

Reaching a negotiated agreement on the archipelago will allow the UK and Mauritius, as close Commonwealth partners, to work even more closely together. This will help us to tackle the regional and global security challenges that we both face, along with our wider partners, and avoid the expansion of malign influences into the Indian ocean. It will include promoting human rights and maritime security while tackling illegal migration, drugs and arms trafficking.

We are also keen to strengthen significantly our co-operation with Mauritius on marine and environmental protection in particular. My hon. Friend the Member for Crawley (Henry Smith) set out some historical issues where those challenges were perhaps not managed as well as they needed to be. The archipelago boasts incredible marine biodiversity, as well as some of the cleanest seas and healthiest reef systems in the world. They support six times more fish than any other Indian ocean reef.

The marine protected area is one of the largest in the world. It prohibits all commercial fishing and extractive activities, such as mining for minerals, oil and gas, and it forms a substantial part of the UK Government’s Blue Belt programme. The area hosts many scientific expeditions, as part of our call for an international target to protect at least 30% of the global oceans by 2030. We will push for this ambitious target at COP15 in the weeks ahead.

We recognise the views of the diverse Chagossian communities in the United Kingdom, Mauritius and the Seychelles. We recognise the diversity of views in those communities and we take those views very seriously. Although the negotiations are between the UK and Mauritius, we will ensure that we engage with the communities as negotiations progress, and I note the kind invitation from my hon. Friend the Member for Peterborough (Paul Bristow) to meet some of those communities.

The UK has expressed our profound and deep regret about the manner in which Chagossians were removed from the islands in the late 1960s and early 1970s, and colleagues have done so again today. I hope that sense of horror and dismay at what happened all those decades ago continues to be reiterated. We are committed to supporting Chagossians, wherever they live, through the £40 million Chagossian support package, which is funding projects in the UK and overseas. I commit to writing to the hon. Member for Wythenshawe and Sale East (Mike Kane) to set out in more detail how that work is progressing.

We have taken other steps to support the community. On 23 November, the UK Government launched a new route to British citizenship for all Chagossian people and their children, free of charge. This new route will give anyone of Chagossian descent the opportunity to build their future in the United Kingdom should they wish to do so, holding British citizenship.

I have talked about ways in which the UK and Mauritius could strengthen our work together. The backdrop to this is our close Commonwealth partnership and our deep historical ties. We are the second biggest export market for Mauritius, while Mauritius is our sixth biggest market in Africa for trade and investment. We are proud of the active Mauritian diaspora in the UK, and hundreds of Mauritian students study in our universities every year. Meanwhile, our tourists flock to Mauritius, accounting for 15% of its visitors annually.

Mauritius is a leader among small island states in tackling climate change. The UK welcomes it as a new pioneer country for the Taskforce on Access to Climate Finance and will act as an anchor donor for Mauritius.

Daniel Kawczynski

I am very grateful to my right hon. Friend for giving way. The main tenet of my discourse this afternoon was to try to get a commitment from her for a referendum of the Chagossian people before any decision is taken. Can she give me that commitment?

Anne-Marie Trevelyan

As I have set out, we will be making sure that we have close discussions, not only with Mauritians but with those communities as well. As the negotiations progress, we will keep colleagues and Parliament abreast of how they are developing.

As we look forward, we aim to work even more closely with Mauritius to tackle the incredibly important regional and global security challenges that we all face. We remain fully committed to ensuring the effectiveness of the base on Diego Garcia, for the benefit of regional and global security.

Daniel Kawczynski

I am very grateful to my right hon. Friend the Minister for the assurances that she has given, and for agreeing to write to the shadow Minister, the hon. Member for Cardiff South and Penarth (Stephen Doughty), on some of the points that he raised.

I heard the Minister say that there will be extensive consultation with the Chagossians, but I still have not heard from her lips that there will be an internationally recognised referendum. My hon. Friend the Member for Rochford and Southend East (Sir James Duddridge) rightly asked questions about how it would come about—the matrix, framework, dynamics and legality of it. I could not agree with him more. There have been referenda in other parts of the world under difficult circumstances and people were able to cast a vote.

I should let my hon. Friend the Member for Crawley (Henry Smith) know that I hope to meet Mr Bontemps next week. Mr Bontemps told me in no uncertain terms that, wherever the Chagossians are—Mauritius, Seychelles, Britain or anywhere else—they are up for remaining British. As part of the British family, our duty and responsibility first and foremost—trumping even international court decisions—is to those Chagossians.
