After meeting Marine Ben McBean for the first time in 2008, Prince Harry declared that the former Royal Marine was 'a hero'. Today, he turned out to roar on Marine McBean, 27, as he completed a gruelling 31-mile run on behalf of the Poppy Appeal - and told the runner to go and have a 'well-deserved beer'. The appearance of the royal came as a complete surprise to Marine McBean, who had designed the route through London using a smartphone app to look like a Royal British Legion poppy.
