Report of the Covenant Design Group
The Covenant Design Group, appointed by the Archbishop of Canterbury on behalf of the Primates of the Anglican Communion, held its first meeting in Nassau, the Bahamas, between Monday, 15th and Thursday, 18th January, 2007.  The Archbishop of the West Indies, the Most Revd Drexel Gomez, chaired the group.
