Jacob Graham, 20, who said he idolized US terrorist Theodore Kaczynski, said he planned to start a "revolution" by killing politicians.

Graham, who said he was motivated by hatred of the government and ecological concerns, described himself as "the first terrorist to grow up in Britain".

The Hugh Baird College student recorded numerous video messages and an online arsenal of firearms and explosives information was found on his computer. The information, which he sent to contacts on Telegram and Discord, included instructions on how to make pipes, nails and car bombs and submachine guns from everyday items.

Graham was found guilty of possessing and sharing terrorist material after a five-week trial at Manchester Crown Court. Police searched Graham's home, a computer engineering student, and found a 3D printer and a quantity of chemicals that could be used to print firearm parts for assembly. 

The defendant was sentenced to 13 years in prison and banned from traveling abroad for 30 years. Graham showed no signs of emotion during the trial.
