Will the UK agree to or announce a decision not to transfer sovereignty over Diego Garcia to Mauritius before Aug 1, 2027?

If the UK agrees to or announces a decision not to transfer sovereignty over Diego Garcia to Mauritius before Aug 1, 2027, then the market resolves to Yes. A decision qualifies if the UK government announces that it will not transfer sovereignty over Diego Garcia to Mauritius, including by abandoning the May 22, 2025 UK-Mauritius treaty or agreeing to a replacement arrangement under which the UK retains sovereignty over Diego Garcia. Abandoning, withdrawing from, or superseding that treaty qualifies only if the UK does not, at the same time, agree to, announce, or state its intention to pursue another arrangement under which Mauritius would become sovereign over Diego Garcia. Changes to payments, the duration or terms of the UK's use of Diego Garcia, security provisions, implementation dates, or other treaty provisions do not qualify if Mauritius would still become sovereign over Diego Garcia. An agreement or announcement qualifies if it involves any of the following: Formal signing of treaties Parliamentary approval with binding effect Official ratification Formal commitment by the head of state/government with constitutional authority Official statements by authorized ministers Official press releases Formal declarations during government proceedings Official statements to international bodies Phased implementation announcements and multi-party agreements where the country is a signatory also qualify. The following do NOT qualify: Preliminary discussions Conditional agreements contingent on circumstances Opposition party statements Leaked documents Think-tank recommendations General aspirations without specific commitment Draft legislation without approval Regional actions (unless specified) Retraction of previously announced commitments
