A FTSE 100 landlord, a French bank and a Middle Eastern country are among the biggest owners of property in the City of London, according to new data seen exclusively by City A.M..However, the data, by proptech firm Datscha using figures from the Land Registry, shows the Corporation of London owns more land than anyone else in the City, with just under 13m sq ft of property. Notable holdings including the Guildhall, the Monument and Mansion House, as well as Tower, London, Southwark, Millennium and Blackfriars bridges. The Corporation of London's holding has been accrued gradually, over centuries, as it helped the Crown to fund wars in exchange for property. Following the City of London in the rankings is British Land, with 2.7m sq ft of space - although at the beginning of the month it emerged the company will reduce its space in the City significantly, with plans to flog its 50 per cent stake it owns in the 908,700 sq ft Cheesegrater for £1.15bn to CC Land.Transport operators Transport for London and Network Rail take third and fourth places in the list, each with around 2.6m sq ft of space.Foreign governments also make up two of the top 20, with Norway in 18th position, with 556,000 sq ft of property, and the government of Kuwait at number seven, with just over 1m sq ft. It's worth pointing out that although Kuwait bought City Airport alongside a consortium of buyers back in 2016, the airport isn't technically in the City.Earlier this month figures from Datscha showed Canary Wharf Group, joint-owned by Qatari Diar and Brookfield, is London's largest landowner, with 21.5m sq ft of property, while the City came second, with 17.4m sq ft of space.
