Its true so far as it goes it is the established church in England the Dicoese of Gibraltar in Europe forms a part of the Church of England but not the established church its Diocesan is not entitled to a seat in the Lords for example  Similarly Sodor and Man is not entitled to a seat in the Lrods but does sit in some capacity in the House of Keys the Channel Islands are also interesting not part of the UK in church terms they are an integral par of the Anglican Diocese of Portsmouth and Im really not sure of the consitutional position of the church there  Theres the added complication that the boundary between the Church of England and Church in Wales doesnt follow the civil boundaries so some Welsh parishes are still in the Church of England and some English in CinW  Try and sumamrise that succinctly enough for the lead  But in generla terms we problem ought to deal a little more with the historical aspects thoguh clearly much would belong in History of the Church of England and also in discussing the formation of the Anglican Communion
