Any parallel structure would exist to support Anglican clergy and congregations that are opposed to women's ordination on the basis of St Paul's assertion that the man is the head of the woman. The alternative Anglican church would also take a conservative stance on the gay issue and oppose gay marriage.

The plan will be debated by the leadership of the Global Anglican Futures Conference, or Gafcon, when they meet in London this week. Gafcon was launched at a meeting in Jerusalem in 2008 as part of the long-running struggle by conservatives to cater to those opposed to the more liberal direction the western Anglican church was headed in.

In an Easter pastoral letter to supporters, Archbishop Eliud Wabukala, primate of Kenya and chairman of the Gafcon primates' council, said: "We shall take counsel together so that our movement can grow strongly and be equipped to fulfil the vision of restoring the Anglican Communion's commitment to biblical truth."

He called for Christians to remain strong.

"If we look just on the surface of things, it is easy to be discouraged. While in Africa and the Middle East Christian communities are being destroyed and intimidated by Islamic radicalism, in the West we are seeing the faith for which these believers are dying being betrayed by compromise with an increasingly intolerant secular culture."

Two of the greatest challenges to world Christianity and Gafcon itself are Islamic radicalism and the re-evangelisation of the West, he added.

"At the heart of our response to both must be faithful and costly witness to the gospel by people who are deeply convinced that, in season or out of season, their work will not be useless or wasted because it is done for Christ and in the hope of the resurrection."

He singled out for particular criticism the process set up by the former Archbishop of Canterbury, Dr Rowan Williams, at the 2008 Lambeth Conference as part of his attempt to maintain Anglican unity. "We need an outward looking unity in diversity that serves the truth of the gospel, not the inward looking unity in diversity of projects like 'Continuing Indaba' that open the doors of the Church to a false gospel."

A parallel structure, the Anglican Church in North America, already exists in the US. Influential US commentator George Conger has reported that this church's Archbishop Foley Beach will be among those conservative Anglicans in London at the meeting this week.

Archbishop Wabukala has previously written: "It is becoming clear that we must see the once missionary nations of the West as now themselves mission fields."

The Gafcon primates have already told the the Anglican Mission in England to operate outside the structures of the Church of England as a missionary society, where necessary.
