On 10 November 1481 a group of nine men, among whom Gunthorpe was named first, obtained a royal licence to found and endow a guild in the parish church of St Mary in North Somercotes,
Lincolnshire. On 9 April 1483, Gunthorpe's patron and benefactor King Edward IV died at Westminster Palace. On 10 May Gunthorpe was appointed
Keeper of the Privy Seal under the authority of Richard of Gloucester. Richard had formally been named protector two days before and as King Richard III he reappointed Gunthorpe on 27 June The appointment was reiterated on 6 July, the day of Richard's magnificent coronation ceremony in
Westminster Abbey. John was the only Keeper of the Privy Seal to serve Richard III. He was not seen as a very wise choice of keeper since he was the former secretary of Queen Elizabeth, and Richard was fearful of a Woodville faction in 1483. While serving as Keeper of the Privy Seal, Gunthorpe served his king in Anglo-Scottish diplomacy by truce-making in Scotland, and extension of a truce with Francis II, Duke of
Brittany; he also helped work out a truce with the Tudor family in Brittany in October 1483, which was extended to 1492 ==Why picked?==
