Thames Valley Police and the South East Counter Terrorism Unit have issued a statement following the "open" verdict into the death of Russian Boris Berezovsky. He was found dead at his ex-wife's mansion in Ascot last year.
It said the two organisations had "carried out a thorough investigation into the unexplained death of Platon Elenin formerly known as Boris Berezovsky."
The investigation included the deployment of an experienced Home Office pathologist to examine the body in situ and conduct the subsequent post mortem.
His findings were considered alongside examination of the ligature, detailed toxicology, physical evidence recovered from the scene and the deceased’s medical history.
The investigation could find nothing to support the hypothesis of third party involvement.

In reaching his verdict the Coroner Mr Bedford made it clear he had no criticism of the police investigation. He stated that his open verdict was as a consequence of conflicting expert testimony regarding pathology.
It is proper for the investigation to consider the alternative pathology position. This position was only brought to police attention immediately before the inquest.
We would stress that the coroner has not specifically requested that any additional work take place. We will continue to liaise with family members as we have done throughout this process."
The Russian oligarch Boris Berezovsky, found dead at his Berkshire home, became a "broken man" and spoke of killing himself after losing a multibillion-pound legal battle with Chelsea Football Club owner Roman Abramovich, his inquest has heard.
His body was discovered slumped on the floor by his bodyguard at his ex-wife's luxury home in Ascot last March.
His death came months after his case involving billionaire Mr Abramovich ended in defeat - costing him millions of pounds and altering his personality, the hearing was told.
The inquest into the death of Boris Berezovsky has been opened and adjourned. There was a brief account of the circumstances around the discovery of the body.
He was found with material around his neck and also a piece of similar material tied around a shower nearby. There is no evidence of third party involvement. However, investigations are still ongoing, so this possibility cannot be eliminated.
Police are still waiting for toxicology reports and the house where he lived in Ascot remains 'under police control' as searches continue.
Berezovsky's body was formally identified this week by his eldest daughter.
The family of Boris Berezovsky’s second wife Galina Besharova have released a tribute to him through Thames Valley Police.
Mr Berezovsky had two children from this marriage, a son and a daughter.
The tribute, which is written by Mr Berezovsky’s daughter Anastasia on behalf of the family, reads: “My father was not the typical parent, nothing about him was ordinary. He has coloured my life in infinite ways, and I know that what he concerned himself most with was making all his children proud.
“His determination and excitement for every aspect of life is something that stands out in even my earliest memories of him and that will always remain deep in my heart.
“There aren't enough words in any language that can somehow express everything that he was and everything he will continue to be. The only word that comes close is extraordinary.”
