There is a "huge expectation" that legislation to introduce the first women bishops will be given final approval by the General Synod next month, a senior Church of England official said.
The Church faces its most important moment since it backed the introduction of women priests in 1992 when it decides on whether to give final approval to the legislation at its meeting in York, General Synod secretary said.
The legislation failed by just six votes in November 2012 to get the necessary two thirds majority after it was derailed by a group of conservatives and traditionalists opposed to female ordination, causing shock and recrimination inside the Church of England and the wider world.
"There is huge expectation around the Church of England and more widely, that this time the legislation will go through," Mr Fittall said.
The Church of England bishops have also agreed to talks with political parties at Westminster to relax the rules to fast track the first women bishops into the House of Lords.
