The Bedford Estate is an estate in central London owned by the Russell family, which holds the peerage title of Duke of Bedford. The estate was originally based in Covent Garden, then stretched to include Bloomsbury in 1669. The Covent Garden property was sold for £2 million in 1913 by Herbrand Russell, 11th Duke of Bedford, to the MP and land speculator Harry Mallaby-Deeley, who sold his option to the Beecham family for £250,000; the sale was finalised in 1918.
