Trump’s repeated public criticism of the UK-Mauritius sovereignty transfer has frozen implementation of the 2025 agreement and shifted focus to renegotiating or blocking any handover that could jeopardize the joint US-UK naval facility at Diego Garcia. With the deal stalled in British legislation and Washington withholding consent required under the 1965 treaty, no active diplomatic track supports a US purchase or lease of Chagos territory. Recent reporting shows US officials considered but did not prioritize an acquisition option, while UK ministers now plan to defer major movement until after the current administration. The short window before 2027 further reduces the likelihood of an announcement absent a sudden bilateral breakthrough or regional security crisis that forces direct US control.
