CASTRIES: Britain has introduced a visa requirement for Saint Lucians effective from Thursday citing a “notable increase” in nationals from the small Caribbean nation claiming asylum, Saint Lucia’s government said in a statement.

Immigration is one of Britain’s most politically sensitive issues, and Prime Minister Keir Starmer’s government has sought to show it is tightening the system as the ⁠populist Reform UK party ⁠gains ground in opinion polls.

Saint Lucia, a former British colony, has a population of about 180,000. Last year, the World Bank estimated a net emigration of just 23 ⁠people.

Its government said it was actively engaging with British government and would continue talks to “explore pathways for maintaining strong mobility arrangements.”

It said it was informed in a letter dated Wednesday.

Saint Lucia is a member of the Commonwealth, an association of mostly former British colonies. Before the 1970s, nationals of many of ⁠these ⁠had the right to live and work in the UK. Saint Lucians previously needed a 16 pound Electronic Travel Authorization (ETA) to travel to the UK. \

There will be a six-week transition for ETA holders, its government said.

On Tuesday, Britain said it would block study visas for Afghanistan, Cameroon, Myanmar and Sudan and halt work visas for Afghans.
