Debate

Diego Garcia Military Base and British Indian Ocean Territory Bill

Contribution

I rise to speak on the Bill and proposed agreement, with particular focus on its defence implications. Given substantial other ongoing work and the fact that other Committees have looked into it, this is not an issue that our Defence Committee has investigated thus far. Let us not be under any illusion, however: this is a matter of strategic importance, financial prudence and moral responsibility. The British Indian Ocean Territory and in particular the Diego Garcia military base have long served as a cornerstone of our defence and security capabilities, not just for the UK but for our allies in the US and across the Five Eyes community. That is why having their stated support for this deal, in addition to that of India and others, is so vital. The base’s role in disrupting threats to the UK, supporting counter-terror operations against ISIS and protecting us against hostile states must continue. Including the management of the electromagnetic spectrum satellite used for communications and the prevention of other powers operating on the outer islands without permission is vital for countering hostile interference. It is not just a diplomatic formality; it is a strategic firewall against encroachment by hostile states. Maintaining US and UK autonomy on the base cannot be overstated. I note the Government position is that Mauritius will be expeditiously informed of activities. However, I look for reassurance that we do not need to provide Mauritius with advance warning about our operations. I would therefore welcome clarification on that point from the Minister to guarantee that all current and future operations can continue unimpeded.
