French expatriates in Budapest are being monitored as part of a European operation against Russian interference. In France, the DGSI is closely interested in the draft European list put together by Jean-Luc Schaffhauser.

In Hungary, Nicolas de Lamberterie and François Lavallou are close to László Toroczkai, president of the far-right Mi Hazánk (Our Homeland) party. The latter demonstrated against NATO a month after the invasion of Ukraine and spoke out in favor of a return of the Ukrainian region of Transcarpathia to Hungarian rule.
