Among the participants Wednesday will be Amal Fashanu, who recently made a documentary for British TV about homosexuality in soccer, 14 years after her uncle Justin committed suicide.
The career of Fashanu, the first black soccer player to move in a 1 million-pound transfer when he joined Nottingham Forest in 1981, faded after he publicly acknowledged his homosexuality. He was found hanged in a London garage in 1998 at 37.
Cameron described homophobia in soccer as a largely taboo topic.
“It’s obviously quite unlikely that there are no gay Premiership players, and that tells you something about the tolerance within the game,” said Steve Field, Cameron’s spokesman.
