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.”
An inquest is to be opened into the death of the Russian businessman Boris Berezovsky, whose body was found at his home in Mill Lane in Ascot on Saturday 23 March 2013. A formal identification by his next of kin took place on the afternoon of Tuesday 26 March.
Thames Valley Police said the inquest will be opened by HM Coroner for Berkshire Peter Bedford on Thursday 28 March in Windsor.

Thames Valley Police have issued a statement about their investigation into the death of the Russian businessman Boris Berezovsky at his home in Ascot on Saturday 23 March 2013. The lead investigator re-iterated that the police had no evidence of third-party involvement in the tycoon's death.
Thames Valley Police, who are investigating the death of Russian tycoon Boris Berezovsky, have said they have no evidence of any third party involvement, which suggests they probably think he took his own life.
Yet they say they still want to talk to close friends and they are accutely aware of all the suspicions that have been thrown up as a result of this untimely death.
But it has to be said most friends do seem to think he probably took his own life. They talk about him being a broken man.
There was one quote which said the Russians didn't need to kill him because six months ago he was devastated by the British courts - a reference to his legal defeat to Chelsea owner Roman Abramovich.
It cost him £70 million. And, perhaps more importantly for a proud man, it shredded his reputation.
