London, UK - Sportsmen, musicians, artists, political radicals, and religious leaders have all been refused entry to Britain in recent years.
The foreign-born relatives of high-profile British names, including author Ben Elton and former Tory leader Michael Howard, have also been refused.
Among the sportsmen, footballers appear to be the most commonly refused.
