Mark Colbourne, 37, from Southampton in southern England plotted the assassination of Prince Charles in the hope that his red-haired son Harry would become king, a British court heard on Monday.
In a notebook seized by police, Colborne said he wanted to kill “dark haired” people, prosecutor Annabel Darlow told the Old Bailey court in London.
“I want them to see my transition from poor red-haired victimised minority that is constantly walked over to a fully transformed military terrorist,” he wrote.
“I would sacrifice my life for that one shot. Kill Charles and William and Harry become king. Kill the tyrants.”
“I’m looking for major retribution, a mass terrorist attack which will bring to the attention our pain not just mine but my brothers around the world.”
During the trial proceedings on Monday, Darlow said that Colborne “perceived himself as marginalised and belittled by society because he was a white, ginger-haired male”.
Colborne was arrested after his half-brother discovered the chemicals and papers detailing his racial hatred at the family home in Southampton, and called police.
He denies the charges against him.
