The author of an anti-Scientology book is claiming that Tom Cruise influenced Amazon into pulling his book from its site.

The Top Gun star reportedly popped by Amazon headquarters in Seattle to view his new film Valkyrie - and has since come under fire for supposedly persuading bosses to stop selling an anti-Scientology title.

Author and former Scientologist John Duignan told The Sun, “I believe Tom Cruise influenced them.”

But both Tom's rep and Amazon are denying the claims.

“U.K. law gives us no choice but to remove the title from our catalogue,” Amazon said in a statement.
