Found him guilty of preparing terror attack after 14 hours of deliberations

Also plotted a cyanide attack and compared himself to Anders Breivik

A 'ginger extremist' has been found guilty of plotting to kill Prince Charles and Prince Williams so Harry could be king 'for the Aryan people'.

Mark Colborne, 37, likened himself to Norwegian far-right terrorist Anders Breivik and made notes in his diary of his plan to assassinate the royal heirs with a high powered sniper rifle.

The warped Aryan supremacist, who worked in a funeral parlour, also ranted in his diaries about attacking dark-haired Caucasians Jeremy Clarkson and Harriet Harman for insulting ginger people.

He bought the ingredients for deadly poison cyanide over the internet, and stockpiled dust masks, metal filter funnels, plastic syringes and latex gloves, jurors were told.

Colborne was caught after his half brother uncovered chemicals and papers detailing his racial hatred stashed in his bedroom at the family home in Southampton.

Following a retrial at the Old Bailey, he was found guilty by a majority of preparing terrorist acts before his arrest in June last year.

The jury convicted him on the basis that Colborne possessed handwritten notes copied from internet sources such as The Terrorist Handbook, The Complete Improvised Kitchen and The Jolly Roger Cookbook about the production of viable explosives.

They also agreed that he had books with titles including Assorted Nasties, Silent Death and The Poor Man's James Bond, which contained recipes for the production and delivery systems of lethal poisons such as cyanide.

However, the jury rejected aspects of the allegations that he intended to use the chemicals and paraphernalia as part of the terror plot.

As Judge John Bevan QC adjourned sentencing to Tuesday November 3, he commented that it was a 'very strange' case involving a 'very strange person'.

The court heard jobless recluse, who had no real friends, felt alienated and marginalised for being a white, ginger-haired, man and also suffering from agoraphobia and depression.

At the age of 13 he refused to go to classes any more because of the abuse and locked himself away in his first-floor bedroom.

Doted on by his mother Patricia, who was an obsessive hoarder, he ate alone and urinated into cups and bottles rather than go downstairs to the toilet on the ground floor.

His only companion was the family dog - although he would later write about poisoning it.

Alone and isolated, Colborne read Hitler's Mein Kampf repeatedly joined the BNP and developed his own version of Ayran supremacist ideology.

In his notebook, 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.'

He went on to state that he wanted a 'silent rifle', adding: 'Take up a good position and put a bullet in Charles's head.

'He is protected but not too protected. I would sacrifice my life for that one shot. Kill Charles and William and Harry become king. Kill the tyrants.'

Prosecutor Annabel Darlow QC said Colborne's notes expressed hatred for 'non-Aryans' who he referred to as 'blacks and Caucasian idiots'.

Comparing himself to other right-wing extremists, he 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.'

Colborne also boasted how his harmless exterior masked his determination to launch a terror attack, adding: 'I am a man of two faces, a real Jekyll and Hyde character.'

On June 3 last year, Colborne's half brother Kevin was preparing to do some decorating at the family home in Butts Road when he came across some receipts for chemicals.

He became concerned to learn that they included chemicals that could be used for fireworks and told their mother Patricia what he had found.

Together, they went into Colborne's 'extremely cluttered' bedroom and uncovered an assortment of chemicals, the books and other equipment and called the police.

In his defence, Colborne admitted buying the chemicals and writing the diary but dismissed entries as 'angry rants' made when he was off medication for depression.

He said: 'Fantasies about killing people as a hitman - that was my number one fantasy. Terrorism fantasies were sort of subsidiary but my main interest in being a professional hitman had taken over.'

Colborne had faced a retrial after a jury failed to agree a verdict in May.

Speaking after the verdict, Investigating officer Detective Sergeant Andy Hedley said: 'It is clear from our investigation that Mark Colborne is a fantasist who had ideas and plans about committing acts that could cause great harm to other people.

'The 37-year-old went beyond the realms of fantasy when he wrote down his intentions and bought the chemicals that would have enabled him to carry out these plans.

'Fortunately, he didn't ever carry out any of these plans and from all the evidence we found, Colborne had not progressed to actually making poisons or viable devices that would have presented an immediate threat to the community.'

He added: 'I would like to thank and praise Colborne's family who were brave in coming forward to tell us about concerns they had about his behaviour.'
