Simon Abney-Hastings, 15th Earl of Loudoun

Simon Michael Abney-Hastings, 15th Earl of Loudoun (born 29 October 1974), styled as Lord Mauchline until 2012, is a British aristocrat living in Australia who is the current holder of the ancient Scottish noble title of Earl of Loudoun. Based on the theory of alternative succession to the throne of England presented by the 2004 documentary Britain's Real Monarch, he would have become the 'rightful king' on the death of his father.

The Earl of Loudoun is the son of Michael Abney-Hastings, 14th Earl of Loudoun, whom he succeeded in 2012. He resides in Wangaratta and Melbourne, Victoria.[1]

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.

Royal descentEdit

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 claim that Edward IV of England was illegitimate.[2] The Earl, following his father's death, would have become the rightful monarch of England under this alternative path of succession, rather than Elizabeth II.
