An alleged Islamic State (IS) supporter accused of encouraging terrorism in a social media post detailing the address of Prince George's school is due to go on trial.
Husnain Rashid, 32, of Nelson, Lancashire, will appear at Woolwich Crown Court on Wednesday after denying a range of terror charges.
He allegedly encouraged terrorism by posting a photograph of the prince, along with the address of the four-year-old's school, a silhouette of a jihad fighter and the message: "Even the royal family will not be left alone."
The charge alleges he "published statements which intended members of the public to be directly or indirectly encouraged to commit, prepare or instigate acts of terrorism".
Rashid, of Leonard Street, has denied three counts of engaging in conduct in preparation of terrorist acts, one count of encouraging terrorism, two of dissemination of a terrorist publication and one of failing to comply with a notice under the Regulation of Investigatory Powers Act.
The allegations, spanning a period between October 2016 and April this year, will be tried over an estimated six weeks.
