Countess Raine Spencer’s former London apartment costs $10.5 million

The former London home of Princess Diana’s stepmother, the late British socialite Countess Raine Spencer, has hit the market for $10.5million.

Growing up, Diana and her siblings disliked their stepmother — they called her “Acid Raine” and often sang “Raine, Raine, go away!”

Before that, in 1948, Spencer married the Hon. Gerald Legge, heir to Dartmouth Earldom – and the couple shared two houses in Mayfair. One of these is this two bedroom apartment now for sale at 47 Grosvenor Square and a townhouse at 12 Chester St.

Spencer had two sons with Legge.

When Spencer became Westminster City Councilor in 1955, the two Mayfair properties were invaluable – the flat at 47 Grosvenor Square served as her office and political base, while the townhouse at Chester Street served as the family’s primary residence.

Spencer eventually divorced Gerald, but Mayfair remained her home.

When she married her second husband, Diana’s father John Spencer, in 1976, one of her first acts was to persuade him to purchase a first floor apartment at the adjacent 48 Grosvenor Square, a purchase that was approved by real estate agent Peter Wetherell, the founder and managing director , organized by Chairman Wetherell.

“With its iconic address and views of the garden square, this Mayfair apartment at 47 Grosvenor Square offers a discerning buyer a unique opportunity to purchase an empty shell and refurbish and modernize the property to create a beautiful new residence,” Wetherell said in a statement to The Post.

“Once refurbished and fitted out, the apartment would make an excellent long-term investment and London residence.”

Interior photos show what the home would look like when redesigned.

The condo is on the fifth floor and is 2145 square feet.

“Despite its illustrious history, the property is currently an empty shell,” the listing reads, adding that the interiors have the potential to be transformed into a “magnificent new residence.”

Currently the house has two bedrooms with dressing areas and en-suite bathrooms.

There is also a spacious lobby with two separate living areas and a dining area with an integrated cocktail bar that can accommodate up to eight people.

The family kitchen/breakfast room has a separate pantry-utility room. From the kitchen there is a separate staff corridor behind the house which connects the kitchen to the entrance hall to facilitate staff circulation and hospitality.

In 2019, the film Princess Diana’s “Evil” Stepmother premiered on Smithsonian Channel.

The documentary alleged that Diana was staying at her ancestral home, Althorp, in Northamptonshire, England, in 1989, when she was 28, when her anger at her stepmother was boiling over.

The king swore at Countess Raine Spencer – then pushed her so hard she fell down the stairs.

“[Raine] “I was badly bruised and terribly upset,” says Raine’s former personal assistant, Sue Howe, in the documentary. “It was a cruel and heartless thing.”

Though Diana had a turbulent relationship with Spencer, their rivalry turned into friendship.

“They were strong through and through – survivors,” Diana’s former butler, Paul Burrell, told The Post. “They endured adversity and tragedy that eventually brought them together.”

Raine passed away on October 21, 2016 at the age of 87 after losing her battle with cancer.
