Assessment: CONFIRMED
The UK public inquiry chaired by former Supreme Court Justice Lord Anthony Hughes concluded in December 2025 that "the operation to assassinate Sergei Skripal must have been authorized at the highest level, by President Putin." GRU officers Colonel Anatoliy Chepiga (alias "Ruslan Boshirov") and Dr. Alexander Mishkin (alias "Alexander Petrov") were identified as the assassins, with Major General Denis Sergeev overseeing the operation from London. The attack was carried out by GRU Unit 29155, a covert assassination and sabotage squad under the command of Major General Andrey Averyanov.
Background: From GRU Officer to MI6 Double Agent
Sergei Skripal began his military career in 1972 as a sapper-paratrooper in the Soviet Army before being recruited into the GRU, Russia's military intelligence service. He rose to the rank of colonel and served in various postings including assignments in Malta and Spain.
In 1995, while on assignment in Madrid, Skripal was recruited as a double agent by MI6 officer Pablo Miller, who was operating under diplomatic cover in Tallinn, Estonia. For approximately nine years, Skripal provided British intelligence with the identities of roughly 300 Russian intelligence officers working undercover across Europe. According to Russian prosecutors, MI6 paid him approximately $100,000 for the information.
In December 2004, Russia's FSB arrested Skripal. He was tried behind closed doors, convicted of high treason in 2006, and sentenced to 13 years in a penal colony. He served six years before his release became part of the largest East-West spy swap since the Cold War.
On July 9, 2010, at Vienna International Airport, four Western-held intelligence assets — including Skripal — were exchanged for ten Russian sleeper agents who had been arrested in the United States as part of the FBI's "Illegals Program" (among them Anna Chapman). Skripal resettled in Salisbury, Wiltshire, under British protection, where he lived quietly in a modest house at 47 Christie Miller Road. His wife Liudmila died in 2012, and his son Alexander died unexpectedly in Saint Petersburg in 2017.
The Attack: March 4, 2018
On March 4, 2018, Sergei Skripal and his visiting daughter Yulia were found slumped unconscious on a park bench outside the Maltings shopping centre in Salisbury at approximately 4:15 PM. A passerby, a nurse who happened to be off duty, provided initial first aid. Emergency services arrived shortly after.
The nerve agent had been applied to the front door handle of Skripal's home earlier that day. Both Sergei and Yulia had absorbed the Novichok through skin contact when leaving the house. The onset of symptoms was delayed — they managed to drive into town, visit a pub, and eat at a restaurant before collapsing.
Detective Sergeant Nick Bailey of Wiltshire Police, who responded to the scene and later attended Skripal's home, also became critically ill from Novichok exposure. All three were admitted to Salisbury District Hospital in critical condition.
Sergei Skripal spent weeks in a coma before regaining consciousness. Yulia was discharged on April 10, 2018. Sergei was discharged on May 18, 2018. Nick Bailey was released on March 22, describing his experience as one that meant "normal life for me will probably never be the same." The Skripals were placed under new identities by British intelligence and have not been seen publicly since.
What Is Novichok?
Novichok ("newcomer" in Russian) refers to a family of nerve agents developed by the Soviet Union and Russia between 1971 and 1993 under a secret program codenamed "Foliant," carried out at the GosNIIOKhT state chemical research institute. Some variants are estimated to be five to ten times more potent than VX, previously considered the deadliest nerve agent in existence.
Novichok agents work by inhibiting the enzyme acetylcholinesterase, which is responsible for breaking down the neurotransmitter acetylcholine. When the enzyme is blocked, acetylcholine accumulates at nerve junctions, causing continuous and uncontrolled stimulation of muscles and glands. Symptoms include convulsions, constricted pupils, excessive salivation, vomiting, muscle paralysis, and respiratory failure. Effects can begin within 30 seconds to two minutes of exposure. In lethal doses, death occurs by asphyxiation as the respiratory muscles are paralyzed.
The use of Novichok was significant because the agent had been developed exclusively within the Soviet/Russian chemical weapons program, making attribution to a state actor nearly inescapable. The Organisation for the Prohibition of Chemical Weapons (OPCW) confirmed the substance used in the Salisbury attack was a Novichok-type agent of high purity.
Dawn Sturgess: An Innocent Life Lost
Approximately four months after the Skripal attack, on June 30, 2018, Dawn Sturgess's partner Charlie Rowley found what he believed was a discarded perfume bottle — a counterfeit Nina Ricci "Premier Jour" bottle — in a charity bin or park area in Salisbury. The bottle had been used by the GRU operatives to smuggle the Novichok nerve agent into the UK and was discarded after the attack on the Skripals.
Rowley gave the bottle to Sturgess as a gift. That morning, after Rowley assembled the applicator and spilled some of the substance on his hands, Sturgess sprayed it on her wrists. She collapsed within approximately 15 minutes, suffering a catastrophic cardiac arrest and consequent brain injury from oxygen deprivation.
Dawn Sturgess, a 44-year-old mother of three, was taken to Salisbury District Hospital and placed on life support. She never regained consciousness and died on July 8, 2018, after doctors discontinued artificial life support. Rowley was also hospitalized in critical condition but survived, though he has reported lasting health effects.
Sturgess had no connection whatsoever to intelligence operations, espionage, or the Skripal case. She was a vulnerable woman struggling with addiction who was living in a hostel in Amesbury at the time. Her death demonstrated the reckless indifference to civilian life inherent in deploying a military-grade nerve agent in a populated area.
The Assassins: Unmasking GRU Unit 29155
The UK's Metropolitan Police identified the two suspects as "Alexander Petrov" and "Ruslan Boshirov" — aliases on Russian passports with suspiciously sequential serial numbers, indicating they were issued from a special government batch rather than through normal civilian channels.
CCTV footage tracked the men's movements meticulously. They arrived in London from Moscow on March 2, 2018. On March 3, they traveled to Salisbury by train to conduct reconnaissance around the Skripals' home. On March 4, they returned to Salisbury, applied the Novichok to the door handle of 47 Christie Miller Road, and took a late-night flight back to Moscow the same day.
In September and October 2018, the investigative journalism group Bellingcat, working with The Insider (Russia), unmasked both men:
-
"Ruslan Boshirov" was identified as Colonel Anatoliy Vladimirovich Chepiga, a highly decorated GRU officer who had been awarded the Hero of the Russian Federation, one of Russia's highest state honors, reportedly for service in Chechnya. Bellingcat obtained passport file extracts from two separate Russian sources that matched Chepiga's photograph to the man identified as "Boshirov."
-
"Alexander Petrov" was identified as Dr. Alexander Yevgeniyevich Mishkin, a military doctor recruited by the GRU during his medical studies. Until 2014, Mishkin's registered home address in Moscow was Khoroshevskoe Shosse 76B — the headquarters of the GRU.
A third suspect, Major General Denis Sergeev (alias "Sergei Fedotov"), was identified as the operational commander who coordinated the attack from a hotel near Paddington station in London. According to Bellingcat's investigation, Sergeev communicated at least 11 times by telephone during the weekend of the attack with a contact in Moscow.
All three men served in GRU Unit 29155, a covert unit specializing in assassinations, sabotage, and destabilization operations across Europe. The unit, commanded by Major General Andrey Averyanov, has also been linked to the 2014 Vrbetice ammunition depot explosions in the Czech Republic, the 2016 attempted coup in Montenegro, and the 2015 poisoning of Bulgarian arms dealer Emilian Gebrev.
In September 2018, the two suspects appeared on Russian state television channel RT, claiming they had traveled to Salisbury as tourists to visit its famous cathedral. The interview was widely ridiculed.
Diplomatic Fallout
The Skripal poisoning triggered the largest mass expulsion of Russian diplomats in history. The UK expelled 23 Russian diplomats identified as undeclared intelligence agents. In a show of solidarity, 28 countries followed suit:
- The United States expelled 60 Russian diplomats and closed the Russian consulate in Seattle
- 17 EU member states collectively expelled 34 Russian diplomats — including France, Germany, Poland, Italy, Spain, the Czech Republic, and the Netherlands
- Canada expelled 4 Russian diplomats
- Australia expelled 2 Russian diplomats
- Ukraine expelled 13 Russian diplomats
- NATO expelled 7 Russian staff from its headquarters
In total, over 150 Russian diplomats and intelligence officers were expelled worldwide by the end of March 2018. Russia retaliated by expelling 189 diplomats from various countries.
The UK also suspended high-level bilateral contacts with Russia, imposed sanctions, and revoked the invitation to Russia's Foreign Minister to visit London. The incident further deteriorated already strained UK-Russia relations following the 2006 polonium poisoning of Alexander Litvinenko in London.
The 2025 UK Public Inquiry
The Dawn Sturgess Inquiry, chaired by former UK Supreme Court Justice Lord Anthony Hughes, published its findings in December 2025 after extensive hearings. Key conclusions:
- Putin personally authorized the assassination attempt on Skripal
- The attack was not merely revenge but "amounted to a public statement, for both international and domestic consumption, that Russia will act decisively in what it regards as its own interests"
- Putin bore "moral responsibility" for the death of Dawn Sturgess
- The GRU operatives' reckless disposal of the Novichok in a populated area was foreseeable as dangerous to civilians
- The inquiry confirmed the identities of Chepiga, Mishkin, and Sergeev as the perpetrators
Russia dismissed the inquiry's findings and has never cooperated with British investigations.
Why This Case Matters
- The first confirmed use of a chemical weapon on European soil since World War II
- Demonstrated that Russia was willing to deploy a weapon of mass destruction in a NATO ally's territory
- The reckless disposal of Novichok killed an entirely innocent civilian, exposing the indiscriminate danger of such operations
- Bellingcat's open-source investigation set a new standard for identifying covert intelligence operatives using publicly available data
- The unprecedented diplomatic response — 150+ expulsions — represented the most unified Western action against Russia since the Cold War
- The UK public inquiry's 2025 conclusion that Putin personally ordered the attack established the highest-level attribution of a state-sponsored assassination attempt
- Skripal's survival was itself remarkable — Novichok is designed to be lethal, and that both he and Yulia lived speaks to the speed of medical intervention
