Mike Tyson had to cancel several appearances in London to promote his autobiography 'Undisputed Truth' because his prison record bars him from entering the UK.
Anyone sentenced to more than four years in prison are not allowed into the country.
Mike Tyson served three years of a six-year prison sentence in the early 90s for raping beauty queen Desiree Washington.
