A Spanish naval commander working at one of NATO’s most sensitive maritime headquarters was suspended and stripped of his security clearance after his relationship with a Russian-born woman raised concerns about a potential espionage vulnerability.
The officer, whose identity has not been made public, was stationed at NATO’s Allied Maritime Command at Northwood, outside London. The facility serves as a major command center for NATO naval operations and plays a key role in monitoring Russian maritime activity, including submarines, critical undersea infrastructure and vessels associated with Moscow’s so-called shadow fleet.
According to reports, the commander met the 49-year-old woman through the dating app Tinder in late 2024. The woman, identified only as J.W., was born in Russia but holds British and Polish citizenship. The two subsequently began a relationship and lived together.
Security concerns reportedly intensified after the officer brought her to events connected with his work. NATO and Spanish security authorities launched investigations, and the commander was suspended in summer 2025. He has since returned to Spain, and the couple have ended their relationship.
The woman has denied being a Russian intelligence operative and said the Spanish officer did not discuss his work with her.
However, she acknowledged that during a trip to St. Petersburg to visit her ill father, she was approached by a Russian intelligence officer. According to her account, the officer questioned her about NATO’s security investigation and her relationship with the Spanish commander.
The incident underscores growing Western counterintelligence concerns about dating apps and other social platforms being used to identify, approach or potentially recruit military personnel and government officials with access to sensitive information.
German counterintelligence officials previously warned that Russian intelligence services were using dating platforms, including Tinder, to approach politicians and military personnel and gather information related to the war in Ukraine.
The Spanish officer has not been publicly accused of espionage, and there is no evidence that he knowingly provided classified information to Russia.
