ANDREW THROWS FERGIE UNDER THE BUS

Prince tries to save his skin in Epstein fallout

- 

COWARDLY Prince Andrew is flipping on ex-wife Sarah Ferguson by angling to have her ostracized from the British royal family to salvage his own posh lifestyle as the palace grapples with the worsening fallout from the pair's chummy friendship with dead pedophile Jeffrey Epstein, courtiers say.

Insiders dish that King Charles recently informed the Duke and Duchess of York that they're no longer welcome at the traditional royal Christmas retreat at Sandringham, England, after allowing his brother and former sister-in-law to attend other private functions, such as the funeral for the Duchess of Kent.

"There's been talk that Andrew is sweating over his already shaky standing and dreaming up a plan for his ex to take the heat for their association with Epstein," a courtier explains.

The rumored dis-invitation to the Norfolk estate follows the revelation that Fergie sent a groveling email to Epstein, calling him a "steadfast, generous and supreme friend" to the Yorks — after publicly pledging to cut ties with the sketchy financier.
