Calling people knowledgeable about C of E

"The Church of England comprises 44 dioceses, each led by a bishop. The diocesan bishops of Canterbury and York are archbishops, who also have oversight over their respective provinces. The occupants of the five "great sees"—Canterbury, York, London, Durham and Winchester—are always spiritual peers and Lords of Parliament. The Bishop of Sodor and Man and the Bishop of Gibraltar in Europe may not sit in the House of Lords regardless of seniority as their dioceses lie outside Great Britain. (The former, however, sits on the Legislative Council of the Isle of Man ex officio.) Of the remaining 37 bishops, the 21 most senior sit in the House of Lords. Seniority is determined by total length of service as an English diocesan bishop (that is to say, it is not lost by translation to another see).[1][2]

*Theoretically, the power to elect archbishops and bishops is vested in the diocesan cathedral's college of canons. Practically, however, the choice of the archbishop or bishop is made prior to the election. The prime minister chooses from amongst a set of nominees proposed by the Crown Nominations Commission; the sovereign then instructs the college of canons to elect the nominated individual as a bishop or archbishop.*"

I think it's the Church's Synod.
