An Aryan supremacist wrote about his plans to assassinate Prince Charles with a sniper rifle, the Old Bailey heard today.

Mark Colborne, 37, said he was prepared to sacrifice his life to kill the heir to the throne “for the sake of the Aryan people”, the jury was told.

Colborne is accused of plotting an Anders Breivik-style terror attack, motivated by being bullied as a child for having ginger hair.

He had started stockpiling equipment and the ingredients for making cyanide in his bedroom at the home he shared with his mother in Southampton, the court heard.

On the second day of the trial the jury was told of notebook entries found by police when they raided his home last June. In entries from May and June 2012, Colborne writes of his admiration for Breivik, the far-Right extremist who murdered 77 people in Norway in 2011, and the killers of Stephen Lawrence.

“I was waiting for the opportunity to kill. Please let it be Prince Charles. That would be good,” he wrote.

“Take down a silent rifle, take up a good stalker potion and put a bullet in Prince Charles’s head. He is protected but not too protected. I would sacrifice my life for that one-shot kill.” Colborne went on to say that by killing Prince Charles, 66, William and Harry would be king and added: “Kill the tyrants.”

“If I had the right weapon, like a military-grade sniper rifle, I would take out Prince Charles for the sake of the Aryan people,” he wrote. “The first chance I would get, with a rifle, if he crosses my path is to murder Prince Charles.”

The jury was told how Colborne also wrote that he identified with Heinrich Himmler. He planned to spray cyanide at ethnic minorities to publicise his racist beliefs, the court heard.

But it is claimed his plans were foiled when his half-brother Kevin found receipts for chemicals bought on Amazon on the landing floor while decorating in June last year and told his mother, Patricia.

Colborne, of Southampton, denies preparing terrorist acts on or before July last year. The trial continues.
