"As with all unexplained deaths, it is being treated as suspicious.
"A post-mortem examination will be held later today to establish the cause of death." Mr Patarkatsishvili's home, Downside Manor, is located in a leafy road in the countryside outside Leatherhead and is reported to be worth £10 million. Police cordoned off the property and were not letting anyone get close to it today.
The manor was also known as Northbury for some time.
The Park was owned for two centuries by the Stydolf family and the diarist John Evelyn records a visit in August 1655 to both Box Hill, Surrey and Norbury Park, which was then owned by Sir Francis Stydolf.
Box Hill, to the south-east, was once part of the estate.
A small Bronze Age hoard consisting of two palstave axes and a scabbard chape dating from around 1150-1000 BC was discovered in 2003 in woodland on the western side of the park.
Mr Reynolds added: “We want to make the most of the site’s great location, and the best way to do this is to regenerate it for housing.
We know that the demand is there in the local community and believe our plans will complement the town’s future growth aspirations, such as Transform Leatherhead, further adding to its vibrancy.
