The controversial figure has since announced the book will be self-published, and he will sue the publisher for $10 million for backing out of the deal.

Speaking at a party in Miami that was live streamed on Youtube, Yiannopoulos revealed the name of his publishing company, Dangerous Books, which will be part of new venture Milo Inc.

The 32-year-old — who departed from right-wing website BreitBart earlier this year — also announced the lawsuit, saying he wants “to send them a message that they can never again do this to a libertarian or a conservative.”

A spokesman at Simon & Schuster responded in a message to The Guardian: “Although we have not seen any complaint filed by Mr Yiannopoulos and have not yet been served, we will defend ourselves vigorously against any action he may bring against Threshold Editions and Simon & Schuster. We stand behind our cancellation of Mr Yiannopoulos’s book and believe any suit by him to be entirely without merit.”
