“ Visiting Pope Clement V. on royal business in 1305, Langton appears to have persuaded Clement to suspend Winchelsea; after his return to England he was the chief adviser of Edward I., who had already appointed him the principal executor of his will. ”

“ Suspended from his office, he went to Rome to be tried before Pope Boniface VIII., who referred the case to Winchelsea, archbishop of Canterbury; the archbishop, although Langton’s lifelong enemy, found him innocent, and this sentence was confirmed by Boniface in 1303. Throughout these difficulties, and also during a quarrel with the prince of Wales, afterwards Edward II., the treasurer was loyally supported by the king. ”
