A Ukrainian intelligence chief turned Russian mole has been sentenced to life in prison, prompting MI6 to issue a stark warning about the depth of Kremlin infiltration within Western security services. The case, which unfolded in a closed Kyiv courtroom, marks one of the highest-profile betrayals since the war began. The former head of a counterintelligence unit was found guilty of passing secrets to Moscow, enabling Russian forces to evade Ukrainian ambushes and target key officials.
MI6’s alert, circulated among NATO allies, points to a concerted campaign by Russian intelligence to place agents inside defence and intelligence structures. It conjures memories of historic spy scandals, but with modern stakes: the lives of soldiers and the integrity of alliances. For the Ukrainian intelligence chief, now stripped of rank and condemned to prison, the sentence is final.
But the broader question of trust remains, as Western agencies scramble to tighten vetting in a conflict where every leak is lethal.
