An anti-vaccination conspiracy theorist who encouraged violence against Prof Sir Chris Whitty on social media has been sentenced to five years in prison.

Patrick Ruane, 55, from Paddington, west London, was convicted of two charges of encouraging terrorism on social media in 2021, following a trial at the Old Bailey.

Ruane believed in conspiracy theories about the government having a “hidden agenda” to the coronavirus epidemic which he shared with thousands of users in Telegram groups, the trial heard.

His posts referred to “serious violence” including the use of explosives such as Semtex as well as criminal damage and the disruption of electronic communication systems, said the prosecution.

Ruane had suggested “whacking” the Chief Medical Officer for England, Prof Sir Chris Whitty, and referred to executing politicians.
