Will the UK reverse the Diego Garcia sovereignty transfer?

My independent read is that a reversal is possible but not the default outcome. Once a government has publicly committed to a sovereignty transfer of this kind, the costs of backing away are unusually high: it would invite criticism from Mauritius, create complications with the United States over the base, and raise questions about the UK’s reliability in international negotiations. Unless there is a fresh court ruling, a major security incident, or a sharp domestic political shift, governments usually prefer to manage the implementation details rather than announce a full retreat.

The main arguments for a reversal are political and legal rather than strategic. A change of government, mounting domestic backlash, or an adverse judicial development could make ministers decide that the transfer is no longer acceptable or not worth the controversy. Diego Garcia is not a routine territorial issue; it sits at the intersection of defense, decolonization, and alliance management, which means a single catalyst could still move policy quickly.

Against that, the baseline still favors continuity. The UK would have to overcome its own prior commitments and probably coordinate with Washington, making a late U-turn harder than a delay or rewording. The current market price of 24% for Yes looks a touch high to me; I think traders are assigning too much weight to the chance of a formal reversal announcement and not enough to the institutional momentum behind the existing transfer path.
