The Kapitan Andreevo border control point in Bulgaria, located 1,600 miles from Dover, is a key site for combating people smuggling into the EU. A UK-funded sniffer dog named Adele is used to detect smuggled boats disguised as inflatable items. Despite efforts, the number of illegal crossings has increased in 2025, with over 39,000 arrivals recorded. UK and Bulgarian authorities are collaborating to disrupt organized immigration crime, but challenges remain as illegal immigration continues to rise.
