Mike Tyson is a convicted rapist, and because of that the Government of Great Britain didn't allow him entry into the country. The event occurred back in 2013 while he was promoting his autobiography titled Undisputed Truth. "I have been coming to the UK consistently in the past decade so this change is disheartening since it affects my current entry standing," Tyson later said in a statement. Even though he wasn't allowed into Great Britain, he got to continue his European press tour.
