George Andrew Campbell McMahon (c.1902 – 1970), also known as Jerome Bannigan, was convicted for his failed assassination attempt against King Edward VIII of the United Kingdom at Hyde Park in London in 1936.
McMahon was born as Jerome Bannigan in Govan, on the outskirts of Glasgow, Scotland.
[3] On 16 July 1936, as Edward VIII rode through Hyde Park, following the Colour ceremony, McMahon produced a revolver.
[4] Bystanders—including a Mrs Alice Lawrence, who was standing next to McMahon—and members of the Metropolitan Police reportedly subdued McMahon, after a struggle, during which the unfired revolver fell near the king's horse as it continued down Constitution Hill.
[3] McMahon was subsequently sentenced to 12 months' imprisonment with hard labour on 14 September 1936, for possessing a firearm with intent to endanger life.
