A ginger-haired extremist accused of plotting a copycat Andres Breivik terror attack allegedly wanted to assassinate Prince Charles so Prince Harry would become king, a court has heard.

Loner Mark Colborne, who felt 'marginalised' because of hair colour, allegedly planned to 'take out' the Prince of Wales with a sniper to allow his youngest son to become heir to the throne.

The court heard how the 37-year-old allegedly dreamt up the terror plot at his home in Southampton, in an apparent bid to transform himself from a ginger-haired victim into a notorious military terrorist.

Penning his ambitions, he allegedly wrote how he would become a 'fully-transformed military terrorist' who would be known for 'striking at the hearts of the dark-haired, dark-eyed Caucasian race'.

In a diary entry read to the court, he added: 'Wouldn't it be great to have a military silent rifle, take up a good stealth position and put a bullet in Charles' head. I would sacrifice my life for that one shot.

'Kill Charles and Prince Harry becomes king... Kill the tyrants and become free from tyrannical future rule.'

The Old Bailey heard how, in another entry, Colborne allegedly promised to target the prince 'for the Aryan people', adding: 'If I had the right weapon, military grade sniper rifle, I would take out Prince Charles and a few others for the sake of the Aryan people.

'The first chance I get with a rifle is to murder tyrannical Prince Charles.'

And in a third note, he allegedly wrote: 'The first chance I would get with a rifle if he crosses my path is to murder Prince Charles.'

The court heard how Colborne had a 'troubled childhood' and felt 'belittled by society' because of his ginger hair and pale skin.

In another entry read to the court, he allegedly wrote: 'I want my legacy to say that I fought a one man war against the capitalist regime.

'I want them to see my transition from poor red-haired victimised minority that is constantly walked over to a fully transformed military terrorist striking at the hearts of the bigoted tyrannical rulers and of course the dark haired dark eyes Caucasian race. I will be heard through terror.'

But the alleged terrorist also used his diary entries to make it clear that he did aspire to be a 'serial killer', instead comparing himself to Norweigan terrorist Anders Breivik.

He wrote: 'I don't want to be a serial killer. I'm more of an Anders Breivik. I have left potential targets open.

'I was waiting for an opportunity to kill one of them. Let it be Prince Charles which would be good.'

Colborne, who suffers from agoraphobia, also wrote in his notebook about his hatred for non-Aryans, blacks and black-haired Caucasians, the court heard.

He also referred to attacking a 'n*****' in a park and doing 'another Stephen Lawrence'.

In one entry dated 20 May 2012 he said he wanted to perform a 'strategic coordinated different attacks on the system's tyrants and tyrants in and around the septic island'.

The following year he wrote about finding information about building 'nerve gases which are as deadly as small-yield nukes.'

Colborne added: 'I'm stuck between committing mass destruction using a weapon of mass destruction and just targeting tyrants.

'I have often wanted to smear toxin on their door handles that in time seeps through their skin and kills them but doing it to more than one neighbour would arouse suspicion.'

The jury heard how Colborne's handwritten notes included the boast that he would put a 'major dent in England' that is 'felt around the world'.

The Old Bailey was told he planned to spray the deadly poison at ethnic minorities to publicise his racist beliefs around the world.

But Colborne's 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.

When police were called they found books about poisons and explosives titled 'Silent Death', 'Assorted Nasties', and 'The Poor Man's James Bond', the court heard.

Detectives also found spray bottles which could be used to squirt cyanide at his victims and a chemical that helped poisons penetrate through the skin, it is claimed.

Colborne also had two leaflets from the British National Party.

In a witness statement read to the court, his half-brother said he knew his brother had bought a copy of Hitler's Mein Kampf but that the racist views came as a 'complete and unpleasant shock'.

Kevin Colborne said: 'I had no idea of Mark's interests or feelings about such topics. I had no idea he disliked non-whites.

'I recall him buying Hitler's Mein Kampf about eight or nine years ago but lots of people do that and it doesn't mean they are racists.

'I am not aware of him belonging to any extremist groups such as the English Defence League. Mum did tell me that Mark had joined the BNP but she told him to unsubscribe.'

Mr Colborne added that, when he made the discovery, he had gone into his brother's room with his girlfriend Kayleigh Uglow to do some decorates.

There, he found receipts for pine charcoal and sodium phosphate and discovered on Google they were used for explosives.

Shocked by what he had found, he told the court that he drove to see his mother Patricia at the Animal Rescue where she worked. They then met at the house to investigate further.

He said: 'Mum was the first person into the room... She picked up a cardboard box and we gathered round. I can recall pulling out a bottle of distilled water, scales, iron oxide and a brown bottle.

'Mum was having a look around and also on the floor. She found a book called Assorted Nasties. It appeared to be a book on poisons and how they could be used.'

The court heard how his mother wanted to talk to the defendant when he returned from college in Southampton rather than go to the police. But Mr Colborne said he had wanted police involvement.

He told the court how he found a book titled 'How to Kill People' with some more receipts tucked into the chapter on poisons, as well as his diary.

He told the court: 'There were also a number of comments about being attacked and abused when younger... and being laughed at and bullied because he was ginger. All of what I had found scared and concerned me greatly.'

Mr Colborne then phoned police to report what had happened, without telling his mother.

'She was socked and upset at what I had done,' he added. 'She was hoping to sort this out the medical way rather than the police criminal way.'

The defendant, who had been to college, was then picked up by his support worker from the Toys R Us car park in Southampton and brought home, jurors heard.

The court heard that the Colborne house was a 'mess' because Patricia was a hoarder and the defendant was agoraphobic.

The defendant kept cups of urine in his room and his belongings spilled into the corridor, jurors were told.

Kayleigh Uglow said in a statement: 'I always found Mark Colborne very quiet and he would spend much time alone in his room. He would always eat alone due to his condition.

'Mark loves animals. He pays more attention to his dog than his family. In many ways Mark is quite childlike.'

Prosecutor Annabel Darlow QC has told the jury: 'He clearly had experienced a troubled childhood and perceived himself as marginalised and belittled by society because he was a white, ginger-haired male.'

The prosecution claim Colborne had 'moved ineluctably from the realms of fantasy into reality.'

Miss Darlow said: 'He commence preparing for an act of terrorism and had taken a number of discrete planned steps to acquire the chemicals, equipment and apparatus required to manufacture cyanide, which he would have the ability to carry and administer either by hypodermic syringe or by spraying the toxin from a bottle.'
