Two men were found guilty Monday of conspiring to commit arson attacks against a car and two properties linked to Prime Minister Sir Keir Starmer [1].

The convictions mark a significant escalation in threats against the UK's top leadership, highlighting vulnerabilities in the security of properties associated with the Prime Minister.

Roman Lavrynovych, 22, and Stanislav Carpiuc, 27, were convicted at the Old Bailey in London [2]. The jury determined that the pair conspired to target three specific locations [3]. These included a car in Kentish Town, north London, and two other properties [1].

Court records indicate the arson attacks took place in May 2025 [1]. Prosecutors said the actions posed a serious threat to life and were designed to intimidate the Prime Minister [1].

Lavrynovych is Ukrainian [2]. Reports regarding the nationality of Carpiuc differ, with some sources identifying him as Romanian and others as Ukrainian [2].

While the court focused on the conspiracy of the two men, separate investigations have looked into the origins of the plot. A BBC investigation suggested that a Russian diplomat may have been the mastermind behind the attacks [4].

Sentencing for the two men will follow the verdict delivered on June 15, 2026 [3].

“The attacks posed a serious threat to life and were intended to intimidate the Prime Minister”

These convictions underscore a growing concern regarding foreign interference and targeted political violence within the UK. The potential involvement of a foreign diplomat suggests that the attacks were not merely random acts of vandalism but coordinated efforts to destabilize the Prime Minister's administration through intimidation.
