*Former boxing champion Mike Tyson has been forced to cancel a number of press events in London after U.K. immigration officials banned him from entering the country due to his 1992 rape conviction.

The new Broadway star was due to promote his autobiography Undisputed Truth in the city this week, but a change in British immigration laws means anyone who has been sentenced to more than four years in prison is barred from entry. Tyson served half of a six-year sentence for the 1992 conviction.

As a result, Iron Mike has instead headed to Paris to salvage his European book tour, which was expected to include a London book signing and a question-and-answer session with fans in a boxing ring.

A spokesman for the book’s publishers HarperCollins says, “There was a change in the U.K. immigration law in December 2012 of which we were unaware.”

The immigration change has also put his 2014 U.K. stage production of his one-man show, “Mike Tyson: Undisputed Truth,” in jeopardy. The 47-year-old was due to begin a touring production of his Broadway hit in March (14).

Producers and director Spike Lee have yet to issue a statement about how the law will affect their plans.
