In a bombshell that has rocked Buckingham Palace to its core, Princess Beatrice and Princess Eugenie have reportedly struck a clandestine agreement with King Charles that could finally end the years-long York family nightmare – but at a price nobody saw coming.

Sources inside the royal households claim the two sisters were summoned to a private crisis summit at Windsor last week, where Charles laid his cards on the table: Prince Andrew must permanently vacate Royal Lodge and surrender his £30 million home within the next six months, or face having his remaining annual allowance slashed to zero.

But instead of the expected tears and tantrums, Beatrice and Eugenie stunned the King by calmly presenting a counter-offer that left even the most seasoned courtiers open-mouthed.

“They told Charles they would personally oversee their father’s move out of Royal Lodge – on one non-negotiable condition,” a senior palace insider revealed. “That Beatrice and Eugenie themselves are granted the right to take over the 30-year lease on the property the moment Andrew leaves.”

Yes – you read that correctly.

The York sisters, long portrayed as the innocent victims of their father’s scandals, have allegedly demanded that Royal Lodge – the sprawling 30-room mansion with its swimming pool, 98-acre grounds and priceless location on the Windsor estate – be signed over to them jointly as soon as Andrew is gone.

The twist? They are willing to pay the Crown a peppercorn rent of just £1 a year, arguing that “keeping the house in York family hands” preserves royal dignity far better than letting it fall to outsiders or – worse – being handed to Prince William as part of his future Duchy of Cornwall portfolio.

“Beatrice was ice-cool,” the source continued. “She told the King: ‘Papa will never leave willingly unless he knows the house stays with his daughters. Let us take it on, and we will make sure he moves without a single headline. Refuse, and he digs in for another decade of misery for everyone.’”

Eugenie apparently sealed the deal by adding: “We’ve spent our entire adult lives paying for Daddy’s mistakes. The least the family can do is let us have the one thing he still has left that actually matters.”

King Charles, cornered and desperate to draw a line under the Andrew saga before his much-anticipated Australia tour next year, is said to have agreed in principle – on the condition that the sisters never allow their father to live there again once he vacates.

The final clause that has left courtiers reeling? Beatrice and Eugenie have demanded written confirmation that Royal Lodge will eventually pass to their own children – Sienna Mapelli Mozzi, August Brooksbank, and Beatrice’s unborn second baby – ensuring the York bloodline retains a major Crown Estate residence for generations to come, even if Andrew himself is effectively exiled.

“It’s a masterstroke,” admitted one stunned York family friend. “They’ve turned their father’s downfall into the greatest property coup in modern royal history.”

Andrew, meanwhile, is said to have sobbed when his daughters broke the news, reportedly telling them: “You’ve saved me – and you’ve saved the house.” He has already begun quietly packing up his vast collection of teddy bears, with Frogmore Cottage now the leading contender for his reduced-circumstances future.

Palace officials are frantically trying to keep the deal under wraps, but whispers are spreading fast. William and Kate are understood to be “absolutely livid” at the prospect of the York sisters securing such a prime residence while they squeeze into four-bedroom Adelaide Cottage. One Kensington Palace source fumed: “Beatrice and Eugenie just played the game better than anyone expected. They’ve gone from royal spares to property tycoons overnight.”

As of last night, the lease transfer paperwork is already being drawn up by the Crown Estate’s top lawyers.

The York family nightmare may finally be ending – but with a twist that ensures Princesses Beatrice and Eugenie will never again be seen as the powerless daughters on the sidelines.

They’ve just become two of the most formidable women in the entire monarchy.

And Royal Lodge? It’s staying firmly in York hands – just not the York hands anyone predicted.
