I checked the MI5 file on Ovsepian and for all the publicity about his claim to have been involved in the murder of the IF this only comes down to a copy of a newspaper article from the "Daily Sketch" dated 26/01/32.
A few excerpts:
"He described the terrible night of July 17, 1918, when the whole family perished
"There is no doubt that they all lost their lives" he declared. "The Duchess Anastasia did not escape, I can assure you."
Using the name Georges Agebakoff he went on to say "I was at Ekaterinburg at that time and saw the whole terrible business" He claimed that he served as an officer in the Imperial Army but already had Communist ideas and in 1916 he refused to return to the front. He was sentenced to be shot but this was reduced to exile in Siberia because of his previous gallantry.
When the Revoluition broke out in 1917 I was liberated and appointed a Commissar of the People. I arrived at Ekaterinburg soon after the transfer of the Tsar and his family there. The Imperial Family was assassinated out of fear.
News had reached us that the White Army, under the command of Admiral Kolchak, was not far from Ekaterinburg.
The local Soviet tried to telephone to Moscow for instructions concerning the Tsar, but it was discovered that all telephone and telegraph wires had been cut. There was a meeting and a tribunal decided that the Imperial Family had to die.
It has been rumoured several times that the Grand Duchess Anastasia escaped death and that she now lives in Germany under the name as Mrs Tchaikovsky, and that she has lost her memory since that horrible night. I can assure you that the Grand Duchess Anastasia is dead. She could not possibly have escaped. The house was full of soldiers and the family was packed into a room before being shot. I also affirm that the bodies were not burned as stated in several books. They were thrown in disused pits more that two centuries old."
Not a lot but possibly worth some thought.

ps he had some interesting experiences with Albert Stopford after defecting to the West which I may post at some future point.
