The Duke of York got into a heated argument with his nephew the Duke of Sussex in which “punches were thrown”, according to a new book.

The book, called Entitled: The Rise and Fall of the House of York, claims the two got into a physical altercation during a family gathering in 2013 over “something Andrew said behind Harry’s back”.

In extracts serialised in the Daily Mail, author Andrew Lownie claims the relationship between the Duke of York and his younger nephews, William and Harry, is “problematic”.

The book claims that the alleged 2013 episode saw “Harry get the better of Andrew by all accounts”, with the Duke of Sussex leaving his uncle “with a bloody nose” before their fight was broken up.
