If Members oppose the deal, which of the alternatives do they prefer? Doing this deal on our terms was the sole way to maintain the full and effective operation of the base into the future. That is why, in November 2022, the then Foreign Secretary, the right hon. Member for Braintree (Mr Cleverly), initiated sovereignty negotiations. It is also why my predecessor, Lord Cameron of Chipping Norton, ultimately continued with those negotiations. Under the previous Government, there were 11 rounds of negotiations, the last one held just weeks before the general election was called. In July, this Government inherited unfinished business. The threat was real, and inaction was not a strategy.
Inaction posed several acute risks to the United Kingdom. First, it threatened the UK-US base. From countering malign Iranian activity in the middle east to ensuring a free and open Indo-Pacific, the base is critical for our national security. Without surety of tenure, no base can operate effectively or truly deter our enemies. Critical investment decisions were already being delayed. Secondly, inaction impacted on our relationship with the United States, which neither wanted nor welcomed the legal uncertainty and strongly encouraged us to strike a deal. I am a transatlanticist, and we had to protect that important relationship. Thirdly, inaction undermined our international standing. We are showing that what we mean is what we say, when it comes to international law and our desire for partnerships with the global south. That strengthens our arguments on issues such as Ukraine or the South China sea.
Further legal wrangling served nobody’s interests but our adversaries’. In a more volatile world, a deal benefited us all—the UK, the United States and Mauritius. This Government therefore made striking the best possible deal a priority. We appointed Jonathan Powell as the Prime Minister’s special envoy for these negotiations, and he has worked closely with a brilliant team of civil servants and lawyers. Their goal was a way forward that serves UK national interests, respects the interests of our partners, and upholds the international rule of law. The agreement fulfils these objectives. It is strongly supported by partners, with Present Biden going so far as to “applaud” our achievement within minutes of the announcement. Secretary Blinken and Secretary Austin have also backed this “successful outcome” which “reaffirms” our “special defence relationship”. The agreement has also been welcomed by the Indian Government and commended by the United Nations Secretary-General.
In return for our agreeing to Mauritian sovereignty over the entire islands, including Diego Garcia, the UK-US base has an uncontested long-term future. Base operations will remain under full UK control well into the next century. Mauritius will authorise us to exercise their sovereign rights and authorities in respect of Diego Garcia. This is initially for 99 years, but the UK has the right to extend that. We have full Mauritian backing for robust security arrangements, including to prevent foreign armed forces from accessing or establishing themselves on the outer islands. The base’s long-term future is therefore more secure under this agreement than without it. If that were not the case, I doubt the White House, State Department or Pentagon would have praised the deal so effusively.
The agreement will be underpinned by a financial settlement that is acceptable to both sides. Members will be aware that the Government do not normally reveal payments for our military bases overseas, so it would be inappropriate to publicise further details of those arrangements at this stage.
The agreement also recognises and rights the wrongs of the past. The whole House would agree that the manner in which Chagossians were forcibly removed in the 1960s was deeply wrong and regrettable. Mauritius is now free to implement a resettlement programme to islands other than Diego Garcia. The United Kingdom and Mauritius have also committed to supporting Chagossians’ welfare, establishing a new trust fund capitalised by the UK, and providing additional Government support to Chagossians in the UK. The UK will maintain the pathway for Chagossians to obtain British citizenship. Furthermore, Mauritius and the UK will establish a new programme of visits to the archipelago for Chagossians.
The agreement also ushers in a new era in our relations with Mauritius—a Commonwealth nation and Africa’s leading democracy. We have agreed to intensify co-operation on our shared priorities, including security, growth and the environment. The agreement ensures continued protection of the islands’ unique environment, which is home to over 200 species of coral and over 800 species of fish.
Finally, I reassure the House and all members of the UK family worldwide that the agreement does not signal any change in policy on Britain’s other overseas territories. British sovereignty over the Falkland Islands, Gibraltar and the sovereign base areas is not up for negotiation. The situations are not comparable. That has been acknowledged across our overseas territories. Fabian Picardo, Chief Minister of Gibraltar, vocally supported the agreement, stating that there is “no possible read across” to Gibraltar on the issue of sovereignty. Similarly, the Governor of the Falklands has confirmed that the historical contexts of the Chagos islands and the Falklands are “very different”.
The Government remain firmly committed to modern partnerships with our overseas territories based on mutual consent. After the Mauritian elections, the Government will move towards treaty signature, and it is our intention to pursue ratification in 2025 by submitting the treaty and a Bill to this House for scrutiny. This is a historic moment, a victory for diplomacy. We have saved the base and secured Britain’s national interests for the long term. I commend this statement to the House.
