Simon & Schuster has cancelled the publication of Milo Yiannopoulos’ book, and his fellow Breitbart employees have reportedly threatened to quit if he is not fired

A statement from the publisher late on Monday said: “After careful consideration, Simon & Schuster have cancelled publication of Dangerous by Milo Yiannopoulos.”

Yiannopoulos confirmed the report on Facebook with a post: “They canceled my book.”

He added: “I’ve gone through worse. This will not defeat me.”

The book was reportedly secured for an advance of US$250,000 and was to be published by Simon & Schuster’s conservative imprint, Threshold Editions.

According to Yiannopoulos’ Facebook page, the book–an autobiography titled Dangerous–was due out on 13 June.

It is the third book that Yiannopoulos has announced that has not eventuated.

Simon & Schuster’s decision follows outrage over a recording that appeared to show Yiannopoulos endorsing sex between “younger boys” and older men. The remarks were made during an internet livestream and circulated in an edited video on Twitter.

In the clip, Yiannopoulos said the age of consent was “not this black and white thing” and that relationships “between younger boys and older men … can be hugely positive experiences”.
