The Anglican Communion - the Anglican Church around the world - is in turmoil over the issue of homosexuality.
Traditionalists are strongly opposed to the ordination of gay clergy and the blessing of same-sex relationships whereas liberals are urging tolerance and change.
A rift developed in 2003 after the consecration in the US of an openly gay bishop, Gene Robinson. The ordination of female priests is also a contentious issue.
In June 2008 some 1,100 traditionalist Anglicans gathered in Jerusalem at the Global Anglican Future Conference (Gafcon) to form a network to combat modern trends in the Church.

Primate: Dr Rowan Williams
Number of Anglicans: No figures are available for England (rather than the UK) but the most recent national Social Trends survey found 22.2% of people identified themselves as Anglican when asked. This would give a UK figure of about 13.4 million. However, the Church of England puts the number of regular churchgoers at 1.7m.

History: English Christianity emerged from the missionary work of St Augustine, sent from Rome in 597, and from the work of Celtic missionaries in the north. Separated from Rome in the 16th Century and became Protestant.
Stance on gay issue: The issue came to the fore in 2003 when a gay canon was elected Bishop of Reading. Before he could take up his post there was an outcry and he was persuaded to resign by Archbishop Rowan Williams. Some senior clergy voiced dismay at this. Under Church of England guidance, gay priests can enter civil partnerships as long as they remain celibate.
