Britain's Prince Charles has reportedly "cut off" his younger brother Prince Andrew.
The 66-year-old heir-to-the-throne has always had a strained relationship with his 55-year-old sibling but relations between them are said to have reached an all-time low since Andrew was named in US court papers by Virginia Roberts, who claims she was made to have had sex with the prince by shamed billionaire Jeffrey Epstein when she was just 17.
An insider said: "The froideur is worse than ever. Charles considers the whole sex scandal degrading, damaging and very embarrassing.
"He thinks that his brother has made some very bad decisions but he has said nothing to Andrew, he simply hasn't communicated with him at all. There's been a very icy silence."
While Charles' spokesperson insists the brothers haven't fallen out, insiders insist the prince won't even have his sibling's name mentioned in his presence and no one can see an end to the feud.
One source told the Mail on Sunday newspaper: "I was told never to mention Andrew's name in the Prince of Wales's company."
Another added: "This is no brotherly spat. It is a seismic shift downhill in Charles's relationship with his errant brother which seems terminal.

"Andrew is having to live with the harsh reality that Charles has cut him off and left him out in the cold."
While Buckingham Palace have denied the sex scandal and Queen Elizabeth, Prince Edward and his wife Countess Sophie have all recently appeared in public with Andrew, Charles has refused to get involved.
The source said: "He does not want to become involved in any way. He is very angry that his brother has put the family in this very difficult and embarrassing situation."
And the elder prince is said to disapprove of his brother's relationship with ex-wife Sarah Ferguson.
The insider said:"Then there's the fact that Andrew is still living with his ex-wife and has just bought a very expensive ski chalet with her. Charles thinks Andrew is making a fool of himself where Sarah is concerned."
