“Ginger Extremist” Fantasized About Killing Charles So Harry Could Be King

He stockpiled chemicals and explosives in his family home, and read up online about making bombs and poisons before his family noticed the sinister stash in his messy bedroom and blew him in to police last June.

Judge John Bevan said it was a “very strange” case involving a “very unusual person”.

But following a retrial at the Old Bailey, Colborne has been found guilty by a majority of preparing terrorist acts before his arrest on 3 June past year.

The websites included The Terrorist Handbook, The Complete Improvised Kitchen and The Jolly Roger Cookbook. One read: “Wouldn’t it be great to have a military silent rifle, take up a good stealth position and put a bullet in Charles’ head”. He is protected but not too protected.

Jurors also agreed Colborne had guide books on poisonous chemicals such as cyanide, one of which was called The Poor Man’s James Bond.

During the previous trial, prosecutors said he had likened himself to mass murderer Anders Breivik, while his diary entries revealed he had wanted to “put a bullet” in Prince Charles’ head.

In March a year ago, Colborne bought various ingredients for cyanide, the court heard.

While comparing himself to Brevik, Colborne wrote: “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”. That would be good. I was waiting for an opportunity to kill one of them.

Colborne went on to say that by killing Prince Charles, William and Harry would be king, and added: “Kill the tyrants”.

Mark Colborne, 37, planned to kill Prince Charles so his second son Harry would be closer to taking the throne.

He also wrote of his admiration for the IRA and his hatred for Harriet Harman because she once described red-haired Danny Alexander as “a squirrel”.

He was caught after his half-brother Kevin and came across receipts for chemicals in his bedroom. Colborne made no reaction as the verdict was delivered.

British media said that among the items discovered were chemicals, charcoal, metal pipes and tubes and latex gloves, along with a trove of manuals providing instructions on how to make poisons and use them to kill people. “Terrorism fantasies were sort of subsidiary but my main interest in being a professional hit man had taken over”.

Colborne, who will now be sentenced in November, didn’t possess a job, while the jury also heard that he didn’t have any real friends, and constantly blamed his appearance for his failures.
