The new Archbishop of Canterbury, Rt Rev Justin Welby, in a ceremony at St Paul's Cathedral today, will say that "marriage is between a man and a woman, and always has been", according to a Daily Telegraph source.
Lambeth Palace was keen to stress the view was standard Church of England policy and insisted the Archbishop was not planning to wade into the row by making any formal statements, but was simply ready to respond to any questions he was asked on the issue.
Tory activists claimed today they felt "a sense of betrayal" over the Prime Minister's "bulldozed-through" reforms and handed in a letter to No 10 urging Mr Cameron to rethink the plans.
