The UK is preparing to send a warship to Guyana in a show of diplomatic and military support for the former British colony, the BBC has learned.
It comes after neighbouring Venezuela renewed its claim for a disputed part of Guyanese territory that is rich in oil and minerals.
The Ministry of Defence confirmed HMS Trent would take part in joint exercises after Christmas.
Guyana, a Commonwealth member, is South America’s only English-speaking nation.
HMS Trent – an offshore patrol vessel – had been deployed to the Caribbean to search for drug smugglers but was re-tasked after Venezuela’s government threatened to annex the Essequibo region of Guyana earlier this month.
This raised fears that Venezuela might invade and spark the first interstate war in South America since the Falklands Conflict in 1982.
