The defendant allegedly had a knife in his rucksack when he was arrested by counter-terrorism police on July 11.

Officers had received a tip-off from the FBI that he was allegedly planning to attack a non-believer who he thought had insulted Islam.

He was charged on Sunday July 17, and made his first appearance at the Old Bailey on Thursday.

Wearing a grey sweatshirt and black trousers, the boy confirmed his identity by video-link from youth detention.

At the start of the hearing, Mr Justice Sweeney thanked Rossano Scamardella QC for attending despite defence lawyers’ industrial action and because of the defendant’s age.

The judge told him: “The court would like to thank Mr Scamardella QC for representing the defendant for the best possible reasons – given his age and the potential injustice that may have arisen were he unrepresented.”

A plea hearing will take place on November 4, he said.

The defendant, who cannot be identified given his age, was further remanded.
