Mr Calvin Bailey

I have set out the security and geopolitical importance of the treaty many times in this place, and would therefore have appreciated the opportunity today to engage with detailed scrutiny of the treaty and the defence arrangements it enables. Sadly, that is not the line that the Opposition are going down. Instead, we are faced with a series of wrecking amendments that do not attempt to improve the Bill in any way. They are designed to force the Government to let our allies down, undermining our international credibility and reputation, and creating greater geopolitical risk and legal and security risks to our base on Diego Garcia. If Opposition amendments were passed today, it would be impossible for us to meet our commitments in a timely way by implementing the agreement with Mauritius that Ministers have completed—an agreement that the Conservative Government started and carried through 11 rounds of negotiations but now want to throw back, no matter the damage that it would do to our nations. At no point have they made clear the legal basis for starting the 11 rounds of negotiations in the first instance. I fully understand and sympathise with the motivation behind amendment 9. The creation of the Chagos islands as a separate territory created a deep injustice, because it was bound up in the dispossession of the Chagossians, but that historical injustice cannot simply be undone. We cannot turn back the clock, however much we might want to do so. The question of a right to return is not remotely simple, because access to Diego Garcia is inevitably a serious question of security. People obviously cannot return to exactly where their families lived, because of the highly sensitive military facility that now stands in their place. Perhaps a limited right of return could be negotiated, but that would engage security procedures that are secret and involve the UK and the US as well as Mauritius, as was acknowledged by the right hon. Member for Aldridge-Brownhills (Wendy Morton). The amendment imagines that if the negotiations were rejected by even the narrowest of margins, the entire treaty would fall apart and would need to be renegotiated afresh, significantly increasing geopolitical risk to the base and our interests. Perhaps the Minister could invite some assistance on this point from those who conducted the first 11 rounds of negotiations. Let us get real: there are reasons why international treaties are negotiated by the Government and subject to democratic scrutiny in this House and through these procedures. What the Liberal Democrats are proposing amounts to making a UK foreign and defence policy dependent on a referendum, and that includes vital defence interests that are shared with the US and other allies. That referendum would apparently comprise non-UK citizens just as much as it would British Chagossians. Frankly, I would have thought that the Liberal Democrats more than others would have learned from the disastrous experience of Brexit that making foreign policy by referendum is not the wisest course of action.
