The Colombian presidential runoff now pits Gustavo Petro, a former guerrilla and leftist senator, against Rodolfo Hernández, a populist businessman with overt pro-Trump rhetoric. For UK defence and security monitors, this is not merely a foreign election. It is a strategic pivot in Washington’s backyard that carries direct threat vectors for British interests in Latin America and the Caribbean.
Petro’s platform promises a break from the Uribe-era hardline security policies that have historically aligned with US and UK counter-narcotics objectives. His proposed renegotiation of trade deals and cessation of aerial glyphosate spraying signals a unilateral shift that could cripple intelligence-sharing pipelines on drug trafficking routes. Colombia remains the linchpin of US-led interdiction in the region; any disruption creates operational gaps that hostile state actors, particularly Russia and China, will exploit. Moscow has already deepened ties with Caracas and Managua; a Petro presidency could open a new flank for Russian influence in the Andes.
Conversely, Hernández, a former mayor who campaigned against corruption, has drawn comparisons to Trump for his anti-establishment rhetoric and use of social media to bypass traditional media. His pro-US stance is reassuring but his lack of coherent foreign policy experience raises questions about strategic reliability. A Hernández win would maintain the status quo, but the UK must watch for internal instability if his outsider status leads to governance paralysis.
The real concern for Whitehall is the vulnerability period between the runoff and the inauguration on 7 August. Colombia faces a deteriorating security environment: dissident FARC factions, ELN extortion rings, and organised crime are already probing for weaknesses. A contested election result, particularly if Petro claims fraud, could trigger mass protests or violent clashes. The UK’s defence attaché in Bogotá has flagged that any prolonged political crisis would divert Colombian military resources away from joint counter-narcotics operations and border security, creating a vacuum along the Venezuelan frontier.
This is a classic strategic pivot for hostile actors. Russia, through its Wagner Group mercenaries, and Iran, via Hezbollah-linked money laundering networks, are already embedded in the Tri-Border Area. A distracted Colombia opens a corridor for these groups to expand into the Pacific coast and the Darién Gap, a known smuggling route for weapons and human trafficking towards Central America and the Caribbean. The UK’s overseas territories in the Caribbean, including the Cayman Islands and the British Virgin Islands, become more exposed to financial crime and illicit flows.
On cyber warfare, both campaigns have already been targeted by phishing and disinformation operations, likely originating from groups linked to the Russian GRU or Venezuelan intelligence. The UK’s National Cyber Security Centre should anticipate spillover attacks against British companies with Colombian operations, particularly in mining and energy. Petro’s team has been particularly vulnerable, with leaked internal communications suggesting foreign interference. This plays directly into advantage for state actors seeking to destabilise Colombia’s democratic process and weaken Western alignment.
Logistically, the UK cannot afford inaction. The Royal Navy’s Atlantic Patrol Task (North) should increase maritime surveillance off the Colombian coast. Joint exercises with Colombian marines, scheduled for later this year, must be reviewed to ensure they are not exploited as cover for intelligence collection by adversarial parties. The Foreign Office needs to bolster its Bogotá embassy’s political section and establish a direct liaison with both campaign security teams.
Intelligence failures in Colombia would echo the missteps seen in the 2019 Bolivian crisis, where a contested election led to a vacuum that Moscow quickly filled. The UK’s Joint Intelligence Committee must prioritise Colombia as a Tier 1 watchlist item until the run off is resolved and the new government stabilises. Every move here is a chess piece in the broader competition with revisionist powers. London cannot afford to be checkmated in Latin America.
