While Richard was still in Sicily, word reached the king of the disputes between William Longchamp, whom Richard had left in England, and John, Richard's younger brother. On 2 April 1191 Richard sent Coutances back from Sicily to England. The archbishop landed in England on 27 June, after a short detour to Rome. Coutances received a release from his crusading vow, and returned to England in the company of Richard's mother, Queen Eleanor of Aquitaine. He had a number of royal documents authorising him to settle the disputes, and on 28 July a settlement was reached that left Longchamp in control, although John still retained sufficient power to make Longchamp's grip on the government somewhat insecure. In September, however, Longchamp imprisoned Richard's bastard half-brother, Geoffrey, Archbishop of York, who was attempting to return to England after having been banished by the king. The imprisonment renewed memories of the murder of Thomas Becket almost 20 years earlier, and Geoffrey was quickly released. Longchamp was brought to a council, headed by Coutances and a number of the clerical and lay lords of England, which took place on 5 October 1191 at Loddon Bridge on the River Thames. Longchamp was deposed and exiled, largely because Coutances had a royal document ordering the magnates to obey Coutances' if the archbishop's advice was resisted by Longchamp, which it had been. Although the medieval chronicler Richard of Devizes accused Coutances of duplicity, and of trying to play both sides against the other, the evidence suggests that Coutances was genuinely trying to solve the dispute in the king's interest. Longchamp fled to Normandy, and he was excommunicated by Coutances.
