British Indian Ocean Territory

I am pleased to speak in the debate. However, it is disappointing that His Majesty’s Opposition felt the need to use part of their Opposition day to debate this issue, given that important negotiations continue between His Majesty’s Government and Mauritius on the future of the Chagos islands. It is never wise to give a running commentary on complex negotiations—perhaps the Opposition should have been more patient.

I understand that the negotiations so far have been productive, with both countries reiterating their commitment to finalising a treaty as soon as possible, with terms agreeing to ensure the long-term, secure and effective operation of the existing base of Diego Garcia and Mauritian sovereignty over the archipelago. I believe that the deal will protect UK and US national security interests by ensuring long-term, effective operations of the base.

Since its creation, the British Indian Ocean Territory and the UK-US military base have had a contested existence. It was only a matter of time before the UK would have to choose between breaking international law and negotiating from a position of weakness and risking national security. It was therefore necessary to pursue an agreement to ensure the stability of the base. It is right to give the new US Administration the chance to consider the full agreement properly.

I am pleased that the Government will finance a new trust fund for Mauritius to use in support of the Chagossian community. Together, Mauritius and the UK will also work to start a new programme of visits to the Chagos archipelago for Chagossians. This is a bilateral agreement between the UK and Mauritius. We are mindful that the future of the islands is an important issue for the Chagossian community. Their interests have been an important part of the negotiations. As the UK has previously made clear, the way Chagossians were removed from the Chagos archipelago and the way they were treated thereafter was wrong. The Government have restated their commitment to supporting Chagossians in the UK, with all Chagossians remaining eligible for British citizenship and making a home in the UK. The FCDO has also declared that officials will continue to engage with different Chagossian groups over a range of issues.

The agreement also shuts down any possibility of the Indian ocean being used as a dangerous illegal migration route to the UK, with Mauritius taking responsibility for any future arrivals. I am reassured that Parliament will have the ability to scrutinise the treaty under the Constitutional Reform and Governance Act 2010, as is standard for international agreements.

I am also reassured that this will be a unique agreement. The Government have stressed that it has no bearing on wider UK Government policy regarding the overseas territories. The agreement does not signal any change in policy to Britain’s other overseas territories and past press speculation was factually wrong. The Chagos islands are a very different issue with a very different history. We stand 100% behind the right to self-determination for the people of the Falklands and Gibraltar.

The military base on Diego Garcia is vital to our national security and I welcome the Government taking on the negotiations as the best way to secure the future of the base. The Government inherited a situation where the long-term future of the military base was under threat. I am therefore glad that the Government have secured a deal that protects the base for at least 99 years, a period that can be extended. Within the deal, there will be clear commitments for robust security arrangements. That, along with our guarantees to the Chagossian people, gives me confidence that the Labour Government are doing the right thing.
