The Church of England is the mother church of the Anglican Communion, and traditionally has had a distinctive leadership role even though it does not have the legal right to tell other provinces what to do.

In principle the Covenant's provisions treat the Church of England the same as other churches, except that the Archbishop of Canterbury has a distinctive role.

In practice, how the Church of England votes on the Covenant will have a big impact on its chances of success. If England votes against, there will be precious little credibility in the claim that those who do sign it are the true voice of Anglicanism.

If England votes in favour, it will be a lot easier to demote the provinces which do not sign  to 'second track' status.
