 Alexander, meanwhile, was planning to support James Mór, son of Duke Murdoch, in his claim on the Scottish throne.James Mór had become a serious threat to King James, not merely because was he likely to have the support of Murdoch's former vassals in Lennox, Menteith and Fife, but also because he had obtained the backing of the King of England, who was angry that King James was ignoring his superior status and the terms of his release from captivity in England several years before.Now James Mór had the support of Alexander too.
