The first openly gay bishop in the Anglican Communion must be sacked to save the worldwide church from schism, leading bishops from the developing world have demanded.
Rt Rev Gene Robinson's election by liberal Americans has caused deep divisions and exposed the 80 million-strong Communion to "ridicule", according to the head of the church in Sudan.
The Most Rev Daniel Deng Bul claimed his statement was backed by 200 other bishops from 17 other "Global South" provinces in Africa, Asia and South America.
Coming on the second day of the once-a-decade gathering of Anglican clergy in Canterbury, the Lambeth Conference, the ultimatum undermines efforts by the Archbishop of Canterbury to keep the church united through discussion and development of a new set of rules.
It came as a group commissioned by Dr Rowan Williams admitted the Communion is in "turmoil" over sexuality, with "positions becoming more extreme" among liberals and conservatives.
One in four bishops is staying away from Lambeth in protest at the Episcopal Church of the USA's decision to elect Bishop Robinson in 2003, although conference organisers have refused to issue a list of delegates in case it breaches "privacy law" and threatens the safety of African bishops who have defied a boycott by their hardline leaders.
But Archbishop Deng said he had been determined to attend the meeting to put forward his church's statement that homosexuality is wrong and against scripture, and to condemn liberals in America and Canada who have departed from his view.
The statement read: "This has not only caused deep divisions within the Anglican Communion but it has seriously harmed the Church's witness in Africa and elsewhere, opening the church to ridicule and damaging its credibility in a multi-religious environment
