The U.K. has granted Bounty Killer a temporary visa and he is set to perform a show this Sunday at The Stratford Rex.
Bounty Killer has not signed the Reggae Compassionate Act.
Leading human rights activist Peter Tatchell has said that the Metropolitan police would cancel a concert in London by a reggae artist notorious for his homophobic lyrics if there was a riot, but they ignore "polite, peaceful lobbying.
Mr Tatchell, who is a parliamentary candidate for the Green party, is furious that Bounty Killer has been given permission to perform by the Home Office.
"Police officers are being sacked for being members of the BNP, yet this guy incites murder and they do nothing.
"There is a clear correlation between murder music and homophobic violence, especially in Jamaica, where the release of anti-gay tracks often coincides with a rise in queer-bashing violence," said Mr Tatchell.
