The UK government has halted intelligence sharing with the US following attacks on suspected drug smuggling vessels in the Caribbean. This decision marks a significant departure from the longstanding practice of collaboration between the two allies. The move is reportedly linked to concerns about the legality of lethal US operations off the Latin American coast.
Despite its control over several Caribbean islands, the UK had previously assisted the US Coast Guard in intercepting drug traffickers attempting to transport illicit substances to North America. In the past, joint efforts involved boarding suspicious vessels, confiscating suspected drugs, and detaining crew members.
Prior to the recent developments, the US had provided intelligence to the UK leading to the apprehension of individuals involved in illegal drug trafficking activities. However, President Donald Trump authorized lethal strikes on multiple vessels near Venezuela, triggering objections from British intelligence citing potential violations of international law.
Reports indicate that the UK ceased intelligence sharing over a month ago following the initial strikes in September. The Trump administration alleges the targeted boats were carrying fentanyl, a substance linked to the US opioid crisis. The administration considers those aboard the vessels as “enemy combatants” engaged in conflict with the US, despite questions surrounding the identity and intentions of the individuals targeted.
Tensions have escalated within the US military hierarchy, with Admiral Alvin Holsey of the Southern Command reportedly offering to resign during discussions with Secretary of War Pete Hegseth. Admiral Holsey is expected to step down from his position in December, just a year after assuming the role.
Amidst the backdrop of these events, US Customs and Border Protection data from mid-2025 shows a significant seizure of fentanyl, with the majority intercepted along the southern border with Mexico. The opioid crisis in the US has resulted in a substantial number of fatalities, with fentanyl overdoses contributing to a high number of deaths in recent years.
The Mirror has reached out to the Foreign and Commonwealth Office for comment regarding these developments.
