 At the time of the Salisbury parliament , Hereford was accompanying two of the king 's daughters to Brabant , and could not be present . On his return , however , as Constable of England , he joined Bigod in July in refusing to perform feudal service . The two earls were joined in their opposition by the earls of Arundel and Warwick . The main reasons for the magnates ' defiance was the heavy burden of taxation caused by Edward 's continuous warfare in Wales , France and Scotland . In this they were also joined by Robert Winchelsey , the Archbishop of Canterbury , who was in the midst of an ongoing dispute with the king over clerical taxation . At one point Bohun and Bigod turned up in person at the Exchequer to protest a tax they claimed did not have the consent of the community of the realm . For Hereford there was also a personal element in the opposition to the king , after the humiliation and the affront to his liberties he had suffered over the dispute in the Marches . At a meeting just outside London , Bohun gave an impassioned speech objecting to the king 's abuse of power and demanding the restoration of ancient liberties . The grievances were summarised in a document known as the Remonstrances .
