British officials warn leaders of defence companies that supply weapons and military equipment to Ukraine about an elevated Russian espionage risk. The warning is communicated to chief executives and company staff following concerns about potential Kremlin-linked intelligence activity targeting the sector.

According to the outlet, the notification takes place at a roundtable earlier in the summer between senior government officials and chief executives. The report frames the threat as affecting not only company leaders but also their staff, suggesting heightened security and vigilance across operations tied to Ukraine support.

The available accounts focus primarily on the fact of the warning and the attribution of the threat to Russia, without providing further operational details such as specific plots, named organisations, or any confirmed incidents. Other outlets are not provided here, so differing angles cannot be directly compared beyond the emphasis on spy risks and the roundtable setting.
