Holidaymakers have been given a fresh warning if visiting Sweden as a threat grows this week. UK tourists visiting the European Union holiday hotspot have been issued a warning by experts ahead of the BBC Eurovision Song Contest taking place.

The Foreign Commonwealth and Development Office (FCDO) has urged Britons to stay alert and follow the latest updates and advice if visiting in the coming days. It warns: "The Eurovision song contest will take place in Malmö from 4 May to 11 May. There will be a greater number of people in Malmö during this time.

"Travel around the city may be affected by travel control systems or protests. See safety and security information if you plan to be in Malmö, or attending the event. If you are planning to attend see the Eurovision song contest website for information about ticketing and practical guidance on how to travel around the city.

"Also check information from the Swedish authorities on the kriseinformation website [and] sign up to get email alerts when the FCDO updates this Sweden travel advice page." It added: "Demonstrations in Sweden are usually peaceful. There are likely to be an increased number of protests in Malmö during Eurovision week.

"Where more than one protest happens at the same time, on opposing issues, clashes can occur. Protests can block access routes. Avoid demonstrations wherever possible and follow the advice of the local authorities. For more details, see the Swedish Police website."

The Swedish Police Authority is strengthening its counter-terrorism work in several areas. This is a result of the Swedish Security Service raising the level of terrorist threats targeting Sweden. It said: "We have been working for a long time on enhancing our abilities and we have a robust capacity in all necessary areas."

The UK will be represented at Eurovision by Olly Alexander.
