Once the London home of the Onassis family, 47 Grosvenor Square is on the market at £25 million.

One of the largest and grandest apartments in the square, it has a glamorous history.

The list of celebrities with links to the property include Jackie Kennedy Onassis, opera legend Maria Callas and Greek shipping billionaire Aristotle Onassis.

Built in 1938-39, just before the Second World War, its first owner was Sir John Anderson, 1st Viscount Waverley.

He was Winston Churchill’s wartime Home Secretary and later Chancellor of the Exchequer.

Sir John moved into the property in 1946 and took up the role of Chairman of the Royal Opera House.

It was Sir John who helped welcome Maria Callas to her first performance at the Royal Opera House in 1952.

Maria Callas first met Aristotle Onassis in 1957.
