A gay Ugandan man has been denied a visa to enter Britain because there is a warrant for his arrest in his home country - a warrant that was issued because he is gay. Chris Stentaza had been invited to the UK by the Church of England.  Stentaza had been a teacher at an Anglican run school in Uganda but was fired and forced to go into hiding after speaking at a conference of gay Christians in Manchester 15 months ago. Homosexuality is illegal in Uganda, punishable by lengthy prison terms. Stentaza was rejected for a visa by the British high commission in the Ugandan capital of Kampala based only on the fact that a warrant had been issued on charges of "crimes against nature".
