Prince Andrew himself chose to withdraw from the gathering where his family would be reunited before Prince William, Kate Middleton, or any other member of the royal family could have humiliated him by preventing him from attending King Charles’ pre-Christmas lunch.
According to sources in the UK media, the Duke of York made the choice based on the counsel of Sarah Ferguson, his ex-wife and the mother of his kids.
According to multiple sources, Prince William and Kate Middleton would object to Andrew attending the lunch after he was connected to a Chinese spy in a recent affair.
