After six years, owing to the poverty of the kingdom, it was found impossible to raise the ransom instalment of 1363. David then made for London and sought to get rid of the liability by offering to bequeath Scotland to Edward III, or one of his sons, in return for a cancellation of the ransom. David did this with the full awareness that the Scots would never accept such an arrangement. In 1364, the Scottish parliament indignantly rejected a proposal to make Lionel, Duke of Clarence, the next king. Over the next few years, David strung out secret negotiations with Edward III, which apparently appeased the matter.
