Croatia will require all UK visitors to provide a negative COVID test on arrival from next Monday, regardless of whether they have been double vaccinated.

The tougher rules have been introduced to the ‘worsening epidemiological situation in the UK’, the Croatian National Tourist Board said.

The stricter entry requirements come only a week after the UK government placed Croatia on the green list.

Visitors can opt for an antigen test taken within 48 hours of arrival, or a PCR test carried out within 72 hours, the tourism body said.

The new requirements will also apply to arrivals from Cyprus and Russia.

The news will come as a blow to travellers, who face the cost and inconvenience of yet another test even though they may have received both vaccinations.

Although Britons no longer have to quarantine on return from Croatia, a pre-arrival test and another test two days after landing in the UK are still required.
