Task: Question Answering
Input (English): Passage: John wanted John de Gray, the Bishop of Norwich and one of his own supporters, to be appointed Archbishop of Canterbury after the death of Walter, but the cathedral chapter for Canterbury Cathedral claimed the exclusive right to elect Walter's successor. They favoured Reginald, the chapter's sub-prior. To complicate matters, the bishops of the province of Canterbury also claimed the right to appoint the next archbishop. The chapter secretly elected Reginald and he travelled to Rome to be confirmed; the bishops challenged the appointment and the matter was taken before Innocent. John forced the Canterbury chapter to change their support to John de Gray, and a messenger was sent to Rome to inform the papacy of the new decision. Innocent disavowed both Reginald and John de Gray, and instead appointed his own candidate, Stephen Langton. John refused Innocent's request that he consent to Langton's appointment, but the pope consecrated Langton anyway in June 1207. Question: Who did Innocent disavow?
Output (English): Reginald and John de Gray
