Fashion mogul Dame Vivienne Westwood has been accused of plagiarising parts of her self-titled memoir.

A writer alleges large sections of one of his works have been lifted and passed off as Westwood's own in her book, which was co-written with biographer Ian Kelly.

Paul Gorman claims 29 passages from his 2001 book The Look: Adventures in Rock and Pop Fashion were copied without the proper credit, and he is suing for damages and demanding an apology.

He tells Britain's The Independent newspaper, "I greatly admire Vivienne's achievements but she has been let down badly by her publisher by this sloppy book."

Westwood has also come under fire from Sex Pistols frontman John Lydon over a section in which she claims to have come up with the idea for the band's iconic track Anarchy in the U.K.

He tells the publication, "The silly cow is claiming she had the idea for Anarchy? What a f**king liberty. That's audacity of the highest order. Go back to making frocks."

The book is also believed to be riddled with spelling mistakes and factual errors.
