The heir presumptive to the title is the present holder's brother, the Hon. Marcus William Abney-Hastings (b. 1981).
Through his grandmother Barbara Huddleston Abney-Hastings, 13th Countess of Loudoun, he is directly descended from, and heir-general of George Plantagenet, 1st Duke of Clarence, brother of Edward IV and Richard III. Other notable ancestors include Mary Tudor, Queen of France, Catherine Pole, Margaret Pole, Countess of Salisbury (Catholic martyr, beatified by Pope Leo XIII), Lady Mary Boleyn, King James IV of Scotland, William Cecil, 1st Baron Burghley, and Alice Spencer, Countess of Derby.
In 2004, Britain's Real Monarch—a documentary broadcast on Channel 4 in the United Kingdom—repeated the claim that the Earl's father, as the senior descendant of George Plantagenet, 1st Duke of Clarence, was the rightful King of England. This argument involves the disputed claim that Edward IV of England was illegitimate. The Earl, following his father's death, would have become the rightful monarch of Britain under this alternative path of succession, rather than Elizabeth II.
