The Reverend Jody Stowell, from north west London, and a spokeswoman for Women and the Church, said they were "hopeful" of success in the vote for women bishops.
The Church of England is being given a second chance to back the introduction of women bishops at a key meeting today.
We are hopeful because of all the work that has been done within the General Synod in terms of relationships between people who have different opinions on this.
We would not say we are overly confident at all because it is the same set of people who voted it down in November 2012 so we have to be realistic about that.
